Vapor-Delivered Lubrication of Steel-Steel and Steel-Ceramic Systems. Topical Report, September 1, 1988-December 31, 1990

摘要

Heavy-duty natural gas engines run hot and relatively dry providing more lubricant and lubrication problems in the piston ring-cylinder and valve areas. A potential materials solution to this problem is the use of ceramic bearing surfaces. The objective of the project was the investigation of the wear characteristics and surface interactions of lubricants on ceramic bearing surfaces and compare these results with the behavior of the same lubricants on steel surfaces. The temperature range of interest in these comparisons is 200 to 370 deg C using a four-ball wear tester.
