Wear Testing and Wear Measurement - University of Miskolc

Wear rates are calculated results reflecting wear mass loss, volume loss or linear dimension change under unit applied normal force and/or unit sliding distance. Wear rate can be expressed in many different ways. Examples are listed in Table 1. Wear resistance. Wear resistance is a term frequently used to describe the anti-wear properties of a material.

Concept of the estimated wear amount | Bearings | OILES

Time-based progress of wear. From a viewpoint of steady wear, Type A may be identified with b2 and c2 except for higher wear rate. When a wear time is fully spared, a value of specific wear amount is obtained by connecting between the origin and the end point of b2 or c2, ignoring b1 and c1. Our calculation formula of the estimated wear amount is based on this concept.

Wear - Wikipedia

The wear rate is affected by factors such as type of loading (e.g., impact, static, dynamic), type of motion (e.g., sliding, rolling), temperature, and lubrication, in particular by the process of deposition and wearing out of the boundary lubrication layer. Depending on the tribosystem, different wear types and wear mechanisms can be observed.

4. Reliability and Failure Rates - gatewaycoalition

A way to look at the failure behavior in time is to examine the failure rate. Failure rate is the time rate of change of the probability of failure. Since the latter is generally a function of time, failure rate is also, generally speaking, a function of time. In terms of failure rate, however, one can often obtain some indication as to which of the influencing factors is controlling and at what time it is controlling.
