A rubbing type of friction and wear tester was developed,which can simulate the high rubbing speed and temperature working conditions of seal coatings,especially to evaluate seal coatings/counterparts serve performance.The rotation sample can run stably through an electrical spindle directly driving the load spindle.The precision-feed system can make the translational sample move to the rotation sample accurately.The sample can be heated to the wanted temperature so that the high-temperature experiment can ...
