A CYLINDER AND ASSEMBLED FOUR-BLOCK TYPE TRIBO-TEST: NOVEL METHOD TO STUDY TRIBO-CHEMISTRY OF LUBRICANT AND MATERIAL

A new tribo-tester was developed by modification of the “Falex Pin & Vee-block” type tribo-test (ASTM D 3233).The advantages of the present method are (1) specimen made of various materials is easily jumpsuit available and (2) the specimen is ready to surface analysis without any processing after the tribo-test.Utilities of the new
