It is a protective film obtained by depositing the protective film and forming an interval between segments after the substrate is grooved.
- the protective film of the present invention needs to be in a segment form formed by depositing a film so as to be divided into segments.
- the shape of the segment is not particularly limited, and a triangle, a quadrangle, a circle, or the like can be selected as appropriate.
- the size of this segment is usually selected from one side or an outer diameter of 1 ⁇ m to 3 mm.
- the interval between adjacent segments is usually 0.1 ⁇ m to 1 mm.
- the film thickness of the segment is usually 1 nm to 200 ⁇ m.
- the base material is masked with a drawing material in a size and shape corresponding to the segment interval portion so that a segment having a predetermined form can be obtained.
- Drawing masking can be performed by a drawing mechanism using various printing techniques such as handwriting, inkjet printing, offset printing, gravure printing, flexographic printing, letterpress printing, screen printing, and photolithographic printing.
- inkjet printing or photolithography printing is preferred. This is because the degree of freedom of change is high and application to a three-dimensional substrate is easy.
- the drawing (printing) pattern can be set freely, that is, since a different segment pattern can be attached to one substrate, it is possible to obtain a protective film having an optimum segment structure according to the application. .
- the fact that it is possible to set a drawing (printing) pattern means that marking and naming can be performed using a segment structure protective film. If the substrate is drawn (printed) on a solid surface, the marking / name can be removed by removing (peeling) the drawing material after film formation. Furthermore, by changing the position, size, and range of the segment structure, the width and bending of the groove after removing the drawing material can be freely controlled, and the groove can be easily used as a flow path. Further, the thickness of drawing (printing) can be adjusted. The thickness of the drawing material can be adjusted by overcoating or the like, whereby the thickness of the film can be changed.
- the mesh In drawing (printing), the mesh can be arbitrarily changed, and a fine segment structure and a large segment structure can be set in gradation. This makes it possible to change the amount of light transmitted through the protective film. It is also possible to freely combine patterns (figures), film thicknesses and gradations.
- the drawing material is appropriately selected in consideration of safety, storage stability, applicability (adhesion to the other material, repellency, bleed, wetness, etc.).
- a drawing material (ink) for ink jet printing it is recommended that the pigment has a size of about 1 ⁇ m or less and a viscosity of about 3 mPa ⁇ s or less.
- forced drying such as an electric drying furnace or hot air drying.
- the ink may be supplied from an ink tank, and if the ink is likely to precipitate, it may have a mechanism for stirring or the like so as to obtain an appropriate mixed state before drawing (printing).
- the drawing material may include a conductive material.
- conductive materials are carbon-containing materials and ITO inks.
- a drawing material containing a conductive material can be used as a conductive path when an electrical action is used during film formation.
- the electrical conductivity here is preferably about 10 5 ⁇ ⁇ m or less. This is because this electrical resistivity can ensure conductivity when a voltage of 3 kV or more is applied.

- an example of the insulating material is a polymer material containing silica particles.
- the electrical resistivity of the drawing material is preferably in the range of 10 5 to 10 6 ⁇ ⁇ m.
- the electrical resistivity of the drawing material is from 10 6 to 10 17 ⁇ ⁇ m. It is preferable that it is the range of these. This is because during DLC film formation, the higher the electrical resistivity of the drawing material, the lower the function of the drawing material as an auxiliary electrode, making it difficult for the current to flow, and the film formation rate decreases. This is because a drawing material having an appropriate electrical resistivity can be selected in consideration of the heat resistance of the substrate.
- the drawing material may include a resist material.
- the resist material is a photosensitive polymer material and is cured by a light irradiation (drawing) mechanism, for example, a light beam generated by a laser drawing apparatus or an electron beam drawing apparatus.

- DNQ diazonaphthoquinone
- a groove may be formed on the substrate using a cutting tool, and then a protective film may be deposited to form an interval between segments.

- the depth of the groove in the cutting tool is selected from the range of about 2 ⁇ m to 2 mm.
- the cross-sectional shape of the groove is arbitrary, and for example, a V shape, a U shape, or the like is selected.
- a suitable conventional tool can be used according to the material of the base material and the desired groove size and shape, and for example, a dicer, a diamond micro-luter, or the like can be used.
- a groove depth corresponding to the film thickness that is, a groove depth of a few nanometers to a few hundred micrometers can be obtained.
- a groove having a depth of about 1 mm can be easily produced. Since the deposited film thickness is several nanometers to several hundred micrometers and the groove depth is about 2 ⁇ m to 2 mm, the protective film deposited after grooving the substrate is divided by the groove and segmented. A protective film in the form is obtained.
- the protective film with a segment structure in which a groove having a depth of 1 mm is formed on the base material has a higher wear resistance than that produced by masking with a drawing material. It improves about 1.5 times. This is because the stress applied to the film is reduced by grooving. The effect of grooving is great when the load is relatively low at 1 N or less, and when the vertical load is 1 N or more with a sphere of ⁇ 6 mm, it is more effective that there is no cut. This is because the base material itself is deformed by the incision.
- the protective film having a deep groove produced by the method is effective when severe abrasive wear occurs.
- the shear strength of the substrate surface decreases, when the vertical load (the force with which the mating member presses the protective film) is large during sliding, it specifically corresponds to 1/10 or more of the yield stress of the substrate.

- corners between the upper surface and side surfaces of each segment are not sharp corners but rounded corners. More specifically, 95% or more of the corners are curved with a radius of curvature equal to or greater than the thickness of the protective film. This is because the protective film is deposited via masking, and as a result, the film components (carbon, etc.) deposited on the masked substrate part and in the vicinity of the masked part are blocked. This is because a corner having When this gentle round segment-shaped protective film is used on a machine part, particularly on its sliding surface, it shows the stability of sliding resistance and long-lived utility.

該レジスト材料を乾燥してレジスト層を該基材表面に形成し、
多関節ロボットのアーム部に備えられた光ファイバー製光照射機構を用いて該レジスト層に光照射することにより、該レジスト層の光照射部を硬化し、

(24) 多関節ロボットのアーム部に備えられた切削工具を用いて、基材表面に溝加工をすることを特徴とする、(14)~(18)のいずれか1つに記載の方法。
耐摩耗性向上のための保護膜として用いられる場合、基材に深さ1mmの溝を形成させたセグメント構造の保護膜は、描画材でのマスキングにより作製されたものに比べて耐摩耗性は1.5倍程度向上する。これは、溝加工をすることにより膜にかかる応力が減少するためである。溝加工の効果は1N以下の比較的低荷重の場合に大きく、φ6mmの球で垂直荷重が1N以上の場合には切込みのない方が有効となる。これは切込みを加えたことにより基材自身が変形するためである。
また、アブレッシブ摩耗(破壊された保護膜が摩擦剤となって残りの保護膜を攻撃して摩耗を促進させる)の抑制のためには溝に摩耗粉をトラップするのが有効であるので、本方法により作製した深溝を有する保護膜は、激しいアブレッシブ摩耗が生ずる場合に有効である。ただし、基材表面の耐せん断強度は低下するので、摺動時に垂直荷重(相手材が保護膜を押しつける力)の大きい場合、具体的には基材の降伏応力の1/10以上に相当する押しつけ力が加わる場合には本方法は適当でなく、描画材でのマスキングにより作製されたセグメント構造の保護膜を用いるのが適当である。
図3において、ロボットアームは初期状態ではP0(ホームポジション)にある。ティ−チングボックスの各ボタンを操作し、アームの移動と、各ポイント(P)でのイベント(動作)の指示を選択し、インプットを行う。このシーケンスを繰り返して、最後にE.O.P.(エンドオブプログラム)を入力し、プログラムを完成させる。なお、E.O.P.の時点で、アーム位置はホームポジションになくてもよい。
本発明の一態様では、プリンタヘッドがロボットアーム(三次元移動機構)の動作基準点に合うようにロボットアーム先端に取り付けられてもよい。インク吐出ノズルの並び方およびロボットアームの動きについて、X−Y方向が共通する座標を採用するように、調整することができる。インクが、ドライバーの指示に従い、プリンタヘッドに供給され、ノズルから吐出され、対象物(基材)に吹き付けられ、所望のパターンが描画される。
本発明の別の態様では、プリンタヘッドのかわりに、溝加工のための切削工具を取り付けてもよい。
図7Aは、6軸ロボットとレーザまたは紫外光源を用いた曲面への露光システム図である。図7Bは、照射のモデル図である。図7Bのシステムでは例えばA→B→C→D→Eの運動により常に基材に垂直に光を照射させることが可能である。照射されたレジストのみが硬化して残留させることが可能であり、それによりDLC成膜時のマスクとすることができる。
6軸ロボットを用いて曲面を有する試料(パイプ)の表面に格子状の線を描画した。試料の基材の材質はステンレス鋼である。描画材は高分子にケッチャンブラックを分散させたものを用いた。Teaching機能(ロボット先端を実物(被加工物)の上に持って行き、座標を実物(被加工物)から読み取る機能)を用いてプログラム上で曲面上の軌跡を円弧補完、放物線補完及び自由曲線補完により連続的に形成し、常にロボットのアーム先端が面に垂直になるように描画した。描画速度30mm/sとした。描画材を乾燥させた後に、パルスプラズマCVD法によりDLC膜の成膜を行った。成膜条件は次に示す通りである。
