Abstract
The invention discloses a small-diameter precision steel pipe comprising a steel pipe body, a first composite plated layer, a high-temperature wear resistant composite coating, a second composite plated layer, and a corrosion resistant and wear resistant composite coating. An inner surface of the steel pipe body is covered with the first composite plated layer, while an outer surface of the steel pipe body is covered with the high-temperature wear resistant composite coating, the second composite plated layer and the corrosion resistant and wear resistant composite coating in order from inside to outside. In such a way, the small-diameter precision steel pipe is good in wear resistance and corrosion resistance, and has an effectively prolonged service life.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of small-bore precision tube.
Background technology
Precision tube is a kind of by a kind of high-accuracy tube material after cold-drawn or hot rolling process.Due to precision tube inside and outside wall non-oxidation layer, bear high-pressure non-leakage, in high precision, best bright finish, clod wash be indeformable, enlarging, flattening free from flaw etc. a little, so being mainly used to produce the product of pneumatically or hydraulically element, such as cylinder or oil cylinder, can be seamless pipe, also have welded pipe.The chemical composition of precision tube has carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
But, the anti-wear performance of currently used small-bore precision tube is poor, and Corrosion Protection is poor, and service life is short.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of small-bore precision tube, and anti-wear performance is good, and Corrosion Protection is good, effectively extends service life.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of small-bore precision tube, including: steel pipe body, the first composite deposite, high-temperature wearable composite coating, the second composite deposite and anticorrosion antiwear composite coating, being provided with the first described composite deposite on the inner surface of described steel pipe body, the outer surface of described steel pipe body is disposed with described high-temperature wearable composite coating, the second described composite deposite and described anticorrosion antiwear composite coating outward from interior.
In a preferred embodiment of the present invention, the first described composite deposite is Ni-Co-P ternary alloy nano chemical composite plating.
In a preferred embodiment of the present invention, the second described composite deposite is Ni-CeO2Nano-composite coating.
In a preferred embodiment of the present invention, described anticorrosion antiwear composite coating is epoxy resin-graphene/graphene oxide composite coating.
The invention has the beneficial effects as follows: anti-wear performance of the present invention is good, Corrosion Protection is good, effectively extends service life.
Accompanying drawing explanation

Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of small-bore precision tube, including: steel pipe body the 1, first composite deposite 2, high-temperature wearable composite coating the 3, second composite deposite 4 and anticorrosion antiwear composite coating 5, being provided with the first described composite deposite 2 on the inner surface of described steel pipe body 1, the outer surface of described steel pipe body 1 is disposed with described high-temperature wearable composite coating 3, the second described composite deposite 4 and described anticorrosion antiwear composite coating 5 outward from interior.
In the present invention, the first described composite deposite 2 is Ni-Co-P ternary alloy nano chemical composite plating.
In the present invention, the second described composite deposite 4 is Ni-CeO2Nano-composite coating.
In the present invention, described anticorrosion antiwear composite coating 5 is epoxy resin-graphene/graphene oxide composite coating.
The small-bore precision tube of the present invention provides the benefit that: anti-wear performance of the present invention is good, and Corrosion Protection is good, effectively extends service life.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
