InactiveCN101518935ASolve pollutionIncreased microhardnessLayered productsVacuum evaporation coatingCarbon filmDiamond-like carbon
The invention provides a PVD nano composite ceramic coating screw. A screw substrate (7) is coated with a coating (6) consisting of a bonding layer, a primary wear-resistance layer and a lubricating layer sequentially. The method for manufacturing the screw comprises the following steps: firstly, depositing a 50 to 100 nanometer thick transitional metal bonding layer at an air pressure of 0.1 Pa; secondly, depositing a 2 to 5 micrometer thick composite ceramic layer as the primary wear-resistance layer at a temperature of between 350 and 400 DEG C, a voltage of between -50 and -200 volts and an air pressure of 0.2 to 1Pa; and finally, depositing a 1 to 3 micrometer transitional metal doped diamond carbon film layer as the lubricating layer at a temperature of between 100 and 150 DEG C, a voltage of between -50 and -150 volts and an air pressure of 0.1 to 0.5Pa. Compared with the prior art, the screw has the advantages of having lubricating performance, along with high hardness (more than 40GPa Hv hardness) and excellent wear resistance (friction coefficient about 0.1). The method is free from pollution and the coating has strong adhesive force.
