The author reviews selected experimental results which have contributed to improved
understanding of sliding wear processes. The emphasis is on the chemical and structural …

Results of pin-on-disk sliding tests in vacuum, with copper, Cu Ni, nickel and molybdenum
sliding against iron, indicate that initial transfer events involve discrete fragments. We …

Friction is a complex energy process. The traditional 'laws' of friction cannot reflect its
energetic nature and interdependent phenomena comprising the friction process. The …

Sliding friction and wear in vacuum were studied for 16 combinations of four pure metals
(copper, nickel, iron and molybdenum) from the points of view of adhesion energy and …

The influence of the hardness of the sliding elements on the unlubricated wear of steels has
been investigated using a pin-on-ring configuration. Pins of quenched-and-tempered steel …

Do two different and independent methods of estimating the wear rate of a test sample yield
the same numerical result? Numerical values of specific wear rates estimated on the basis of …

Results obtained in pin-on-ring tests of hardened-and-tempered steel are analysed. It is
shown that the rate of wear can be related to an 'index of wear intensity'. This index is …

A possible procedure is proposed, which basically refers to tribological variables commonly
used in engineering screen tests and in principle allows extended use of experimental wear …

The variation in friction-coefficient with sliding distance for different sliding arrangements for
both similar and dissimilar metals in a tri-pin-on-disk geometry is presented. It is shown that …

This paper describes the application of laser speckle photography to the measurement of
deformations associated with sliding wear. The deformations and the associated strains are …
