A kind of high temperature
alloy group self-lubricating compound material and the method to pattern surface of it. The components and the
mass percent of them are as following: Ni: 28.8-56.8%, Fe: 10.0-30.0%, Cr: 7.2-14.2%, W: 5.0- 15.0%, C: 3.0-6.0%, Si: 0.8%-1.2%, MoS2: 5.0%-15.0%. The method to pattern it' s surface contains the following steps: The surface of the
nickel chromium alloy group self-lubricating compound material sample after being hot pressed and mould will be polished. A gammaray
laser will be used to corrase micropore on the surface, the focus of the focusing lens will be adjusted to 40-60mm, the
facula diameter at the focus is 0.15- 0.20mm, the impulse duration will be adjusted to 450-500ns, the
laser bean will process micropore according to ring shape from outside to inside. The surface after being corrased and polished will be lubricated by daubing the fat of
solid layered
dry lubricant. The
alloy group material not only owns high
mechanical strength but also owns high temperature self-lubricating ability. The
coefficient of friction can be decreased, the application life can be prolonged, and low attrition abrasion in wide temperature range can also be realized by patterning the surface.
