WEAR-RESISTANT COATING OF THE WORK SURFACE OF DISC-SHAPED MACHINE PARTS MADE OF ALUMINUM OR ALUMINUM ALLOYS.

摘要

A wear resistant coating for the working faces of disc-shaped machine parts made of aluminum or aluminum alloys is applied to the parts by thermal spraying. The coating comprises two components, one being aluminum oxide pure or mixed with another oxide and the other aluminum or an aluminum-silicon or aluminum-magnesium alloy. Such a coating, called a cermet, can be used advantageously on brake discs, clutch plates, and the like.
