Abstract
The invention discloses a spatial AAM (anti-abrasive material), and belongs to the field of surface modification. The spatial AAM is in a four-layer structure, and successively comprises a metal substrate layer, a Cr layer, a W-C: H layer and an a-C: H layer, wherein the metal substrate layer is made of stainless steel; the W-C: H layer is made of metal tungsten doped with hydrogen-containing diamond; and the a-C: H layer is made of hydrogen-containing diamond. As for the AAM, the hardness is 2000-3000, the frictional coefficient under a vacuum environment is as low as 0.02-0.1, the adhesion is more than 100mN, the abrasive resistance and abrasive reduction performance, the surface properties of spatial movable parts can be obviously improved, and the service life and reliability of the spatial movable parts can be enhanced.
Description
Technical field
The present invention relates to a kind of space and use anti-abrasive material, belong to the surface-treated field.
Background technology
The space vehicle movable part adopts molybdenumdisulphide as the surface lubrication material, is primarily aimed at anti-attrition, and hardness is lower, and wear resistance is relatively poor, not too is applicable to the surface-treated of high-mechanic transmission class movable part.Along with the increase of space vehicle, be badly in need of improving the abrasion resistance properties of movable part to long lifetime, highly reliable movable part application demand.Therefore must develop a kind of mechanically resistant material that under vacuum environment, has the wear resistant friction reducing performance.
Summary of the invention
The object of the present invention is to provide a kind of space to use anti-abrasive material, said material wear ability and anti-attrition performance are good, can improve the surface property of space operation component significantly, improve its work-ing life and safety.
The object of the invention is realized by following technical scheme:
Anti-abrasive material is used in a kind of space, and said material is made up of four-layer structure, is followed successively by metallic matrix, Cr layer, W-C:H layer and a-C:H layer and constitutes; Wherein metallic matrix is a stainless steel, and the W-C:H layer is that the tungsten doping contains hydrogen diamond, and the a-C:H layer is for containing hydrogen diamond.
Said preparation methods is following:
(1) matting uses sherwood oil, acetone, alcohol that metallic matrix is carried out ultrasonic cleaning respectively;
(2) heat and vacuumize, be in the temperature and vacuum range of setting when guaranteeing thin film deposition;
(3) the plasma source bombardment is cleaned, and feeds argon gas to Vakuumkammer, opens plasma source matrix surface is bombarded cleaning, removes the dirt settling of matrix surface;
(4) deposition Cr layer is opened the Cr target at matrix surface deposition Cr layer, makes Cr layer and matrix surface form strong interface, improves adhesive force;
(5) deposition W-C:H layer is opened the WC target, feeds Ar and C
2H
2, through control W content and H content, obtain to have the W-C:H layer of predetermined hardness, improve the supporting capacity and the wear-resistant ability of film;
(6) deposition a-C:H film feeds C
2H
2Gas through protium content and gradient in the control table tunic, discharges the internal stress of film, reduces the frictional coefficient of film.
Through test, material hardness according to the invention reaches HV2000～3000, and frictional coefficient is low to moderate 0.02～0.1 under the vacuum environment, sticking power＞100mN.
Beneficial effect
