... Abstract This chapter discusses the processes and procedures involved in tribotesting, the significance of test parameters and conditions, and practical considerations including test metrics and measurements and the interpretation of wear damage. It also describes the different types of erosion...

In the blower motor example, it would be appropriate to conduct laboratory wear tests on ABS versus other...

However, this book is mostly about materials, but there are chapters on tribotesting and lubricants. 1.2 Tribology A probable...

... to other soft materials and to itself, and the friction typically is like that of most soft metal couples in the range of about 0.4 to 0.6 in typical tribotester sliding, like a pin-on-disk test. Copper versus 60 HRC steel tends to be lower in friction (maybe 0.4) and adhesive transfer is minimal; mostly...

.... Coefficients of Friction from Tribotesting Chapter 5, “Tribotesting,” in this book will describe tribotesting in detail, but most tribotests have wear of the rubbing members as the test metric. Most wear testers also produce friction data. Usually, testers are computer controlled, and a continuous...

... but can survive often without galling because wear debris forms a separating tribofilm. Limited ASTM G98 galling tests (Bud Labs, the author’s tribotesting company) suggest that the galling threshold stress of 1020 steel with a 4140 steel at 30 HRC counterface is 500 psi; this is a low value.
