Erratum and Discussion. Comments on "A Practical Interpretation of Unlubricated Wear Data for Some Non-Ferrous Metals" by G. Stott and J. Eyre

Bearing materials tested included L65. Continuous condition monitoring likely to gain in importance so that serious lubricant starvation is detected early, and ability to survive these brief periods rather than dry wear behavior is the determining factor. There will be many cases where a combination of a low process roughness and a relatively high wear rate is to be preferred over high roughness and low wear. Speed vs load diagrams relate quantitatively only to the test equipment. The temperature expected in practice should first be estimated, and the test performed under thermal conditions resembling those in practice as closely as possible. Authors' reply: Speed vs load diagrams show that some material combinations are much safer than others. Material selection is carried out at the design stage.6 refs.--EPAA/AF.
