Abstract
Description
L'invention a pour objet un alliage antifriction destiné plus particulièrement au réglage des coussinets de paliers lisses. The subject of the invention is an anti-friction alloy intended more particularly for the adjustment of plain bearing bearings.
Jusqu'à présent pour le réglage des coussinets de paliers lisses fonctionnant sous moyenne et forte sollicitation , par exemple telle que celle de moteurs marins à faible vitesse, de broyeurs à boulets, de compresseurs de gaz, de wagons de chemin de fer, on a appliqué des alliages à base, par exemple, d'étain SnSb11Cu6 (type T83) ou de plomb PbSbSn10Cu (type t10), qui du fait des compositions utilisées sont relativement chers. Hitherto for the adjustment of plain bearing bushings operating under medium and high stress, for example such as that of low speed marine engines, ball mills, gas compressors, railway wagons, applied alloys based on, for example, tin SnSb11Cu6 (type T83) or lead PbSbSn10Cu (type t10), which because of the compositions used are relatively expensive.
Les constructions actuelles de ces dispositifs sont plus poussées et les exigences envers les matériaux antifrictions sont aussi accrues, les alliages connus jusqu'à présent et appliqués s'avèrent donc insuffisants. Il en découle le besoin d'élaborer de meilleurs alliages à meilleur marché par rapport à ceux mis à profit jusqu'à présent ou d'y apporter des perfectionnements importants. The current constructions of these devices are more advanced and the demands on anti-friction materials are also increased, the alloys known until now and applied therefore prove to be insufficient. This results in the need to develop better alloys at a lower cost than those used to date or to make significant improvements.
Les alliages utiles aux exigences accrues impliquées devront prévoir le transfert de pressions, de l'ordre de 12 à 16 MPa (120 à 160 kG/cm) de longue durée à la température de fonctionnement du palier, c'està-dire de 70 à 1200C. Ces alliages devront présenter des propriétés convenables de frottement, de résistance à la corrosion et des propriétés mécaniques mème à une température atteignant 1580C (de courte durée). The alloys useful for the increased requirements involved must provide for the transfer of pressures, of the order of 12 to 16 MPa (120 to 160 kG / cm) of long duration at the operating temperature of the bearing, that is to say from 70 to 1200C. These alloys must have suitable friction properties, corrosion resistance and mechanical properties even at a temperature up to 1580C (short-lived).
De telles conditions sont remplies par les alliages selon l'invention, dont les principaux composants sont le plomb, le cadmium, le zinc, et/ou l'argent constituant la matrice plastique. Comme éléments de renforcement de cette matrice, le plus souvent on applique le calcium, le nickel, le tellure, le scandium, le titane, le cobalt, le hafnium, le niobium, le baryum, l'yttrium, le zirconium, le magnésium, dont le taux total en poids ntexcie pas 2,5 %
La matrice et les éléments de renforcement de cette dernière peuvent être complétés d'éléments qui peuvent être pris comme impuretés, par exemple l'étain, l'antimoine, l'arsenic, dont le teux total en poids est inférieur à 0,05%.Such conditions are met by the alloys according to the invention, the main components of which are lead, cadmium, zinc, and / or the silver constituting the plastic matrix. As reinforcing elements of this matrix, most often calcium, nickel, tellurium, scandium, titanium, cobalt, hafnium, niobium, barium, yttrium, zirconium, magnesium are applied, of which the total rate by weight does not exceed 2.5%
The matrix and the reinforcing elements of the latter can be supplemented with elements which can be taken as impurities, for example tin, antimony, arsenic, whose total teux by weight is less than 0.05% .
La composition nominale en poids de la matrice est égale à : 2,5 à 15,5% de cadmiun, de 0,25 à 2,5% de inc et /ou d'argent, et au minium 77,0% de plomb. The nominal composition by weight of the matrix is equal to: 2.5 to 15.5% of cadmium, from 0.25 to 2.5% of inc and / or of silver, and at least 77.0% of lead .
Les éléments de renforcement seront ajoutés avantageusement aux taux suivants: calcium 0,001 à 1,0% nickel 0,001 à 1,0 baryum 0,001 à 1,0% cobalt 0,001 à 1,0% scandium 0,001 à 2,5% tellure 0,001 à 2,5% vanadium 0,001 à 0,75% titane 0,001 à 0,75% aluminium 0,001 à 1,0% lithium 0,001 à 0,25% niobium 0,001 à 1,0% zirconium 0,001 à 0,25% yttrium 0,001 à 2,5% magnésium 0,001 à 2,5% silicium 0,001 à 0,25% tungstène 0,001 à 0,25% hafnium 0,001 à 0,50% molybdène 0,001 à 0,25% oxygène 0,0001 à 0,25% azote 0,0001 à 0,25% bore 0,0001 à 0,25%
L'alliage selon l'invention subit un traitement par déformation plastique avec un taux de déformation d'au moins 10% avantageusement de 15 à 60%, à une température de 20 à 1350C, puis ensuite un recuit à une température de 20 à 185 C
La quantité d'éléments de renforcement utilisés ainsi que la composition de la matrice sont fonction d'un alliage concret appliqué, donnant une large possiblité de construction de l'alliage selon les exigences individuelles tout en veillant aux frais, à la protection du milieu et à la simplicité du savoir faire pour obtenir cet alliage.The reinforcing elements will be advantageously added at the following rates: calcium 0.001 to 1.0% nickel 0.001 to 1.0 barium 0.001 to 1.0% cobalt 0.001 to 1.0% scandium 0.001 to 2.5% tellurium 0.001 to 2, 5% vanadium 0.001 to 0.75% titanium 0.001 to 0.75% aluminum 0.001 to 1.0% lithium 0.001 to 0.25% niobium 0.001 to 1.0% zirconium 0.001 to 0.25% yttrium 0.001 to 2.5 % magnesium 0.001 to 2.5% silicon 0.001 to 0.25% tungsten 0.001 to 0.25% hafnium 0.001 to 0.50% molybdenum 0.001 to 0.25% oxygen 0.0001 to 0.25% nitrogen 0.0001 to 0.25% boron 0.0001 to 0.25%
The alloy according to the invention undergoes a treatment by plastic deformation with a deformation rate of at least 10% advantageously from 15 to 60%, at a temperature of 20 to 1350C, then then an annealing at a temperature of 20 to 185 VS
The quantity of reinforcing elements used as well as the composition of the matrix depend on a concrete alloy applied, giving a wide possibility of construction of the alloy according to individual requirements while ensuring the costs, the protection of the environment and to the simplicity of the know-how to obtain this alloy.
Les alliages à matrice selon l'invention, renforcés par des éléments convenables de renforcement, présentent de hautes propriétés d'élasticité de l'ordre de 35 à 55% par rapport aux alliages appliqués jusqu'à présent à base d'étain. Ils présentent une plasticité suffisante et de bonnes caractéristiques technologiques. The matrix alloys according to the invention, reinforced with suitable reinforcing elements, have high elasticity properties of the order of 35 to 55% compared to the alloys applied hitherto based on tin. They have sufficient plasticity and good technological characteristics.
La gamme des possibilités de résistance de la matrice et le choix d'éléments de renforcement à l'application concrète, donnent la possibilité d'atteindre les propriétés mécaniques suivantes limite d'élasticité conventionnelle
( Rsn 0,02 ) 95 MPa (9,5 kG/mm2) limite d'étirement conventionnelle
( Re0,2) 110 MPa (11,0 kG/mm2) résistance de séparation (Rm) 125 MPa t12,5 kG/mm2) allongement linéaire (A5) 5 à 8% résilience avec entaille (K ) environ 9,8 à 15,7 J/cm2
( 1 à 1,6 kGm/cm2)
La perte de propriétés d'élasticité à la température de 1500C est très legère , n'excédant pas 35% de la valeur à la température ambiante, ce qui pouve la haute stabilité de l'alliage du point de vue thermique.The range of possibilities of resistance of the matrix and the choice of reinforcing elements to the concrete application, give the possibility of reaching the following mechanical properties conventional elastic limit
(Rsn 0.02) 95 MPa (9.5 kG / mm2) conventional stretch limit
(Re0.2) 110 MPa (11.0 kG / mm2) separation resistance (Rm) 125 MPa t12.5 kG / mm2) linear elongation (A5) 5 to 8% resilience with notch (K) about 9.8 to 15.7 J / cm2
(1 to 1.6 kGm / cm2)
The loss of elasticity properties at the temperature of 1500C is very slight, not exceeding 35% of the value at room temperature, which can give the high stability of the alloy from the thermal point of view.
Il faut aussi souligner que le coefficient de frottement à sec des alliages obtenus avec une telle matrice est exceptionnellement faible, et ils présentent une résistance à la corrosion des acides gras et des alcalis égale à l'alliage à base d'étain. It should also be emphasized that the dry friction coefficient of the alloys obtained with such a matrix is exceptionally low, and they have a resistance to corrosion of fatty acids and alkalis equal to the tin-based alloy.
Durant le fonctionnement, dans ces alliages, on n'observe par de chagement de phase. During operation, in these alloys, no phase change is observed.
Leurs applications apportent des effets économiques importants. Their applications bring significant economic effects.
