M), with the YG6 sintered carbide balls (main component WC-Co) of Ф 9.525mm with ball-disk (Ball-on-disk) way of contact pair
Mill.Wear test equipment is the UMT-3 multifunction friction wear testers of U.S. CE TR companies.Wear test condition is：Low load
Lotus 20N, linear velocity 0.5m/s, testing time 900s.Friction coefficient is directly read by friction device.
By the way that embodiment 1-2 and comparative example 1-3 to be carried out to the reading of friction coefficient, respectively in low load 20N,
Volume erosion rate (W) is as shown in table 1.
By the above results as can be seen that the present invention by adjusting inorganic coating composition, by increase Mn and Ti elements,
Compared to individually use Mo-ZrC, Mo-ZrC-Mn or Mo-ZrC-Ti composite coating, in addition to keep great friction coefficient the characteristics of, simultaneously
It reduces other than its wear rate, also there is excellent corrosion resistance, and there is lower coefficient of thermal expansion.
Applicant states that the present invention illustrates the process of the present invention, but the present invention not office by above-described embodiment
It is limited to above-mentioned processing step, that is, does not mean that the present invention has to rely on above-mentioned processing step and could implement.Technical field
Technical staff it will be clearly understood that any improvement in the present invention, equivalence replacement and auxiliary element to raw material selected by the present invention
Addition, the selection etc. of concrete mode, all fall within protection scope of the present invention and the open scope.
