: special issue devoted to wear.

The nine papers give a good cross-section

of some of the work going on in

Japan. KOSAKA reviews the history of the topic and makes some suggestions for future research. MIZUNO deals with macroscopic analysis, particularly with oxidation of metals. Tsuu~, who has previously worked with TAKAGI, considers some wear phenomena on metal surfaces. MATSUNAGAcontributes a critical survey on the use of electrical contact resistance measurements. AOKI and his observations on fretting of bearing steel in rolling contact.

HIRrlNO and his associates deal with abrasive wear caused by pulverized coal, a subject treated by Dr.Wahl in Germany some thirty years ago; apparently these results have not yet reached Japan. The wear of copper alloys is discussed by HAYAX~ of the Castings Research Laboratory, Waseda University, Tokyo. This paper will have the special attention of a large number of research workers. Unfortunately, no literature is quoted. MATSUBARA continues his work on the wear properties of plastics.

Finally,

Takeyama deals with the wear of cutting tools. On the whole, references to the literature

Book Reviews Braking of Road Vehicles, by T. P. NEWCOMB AND R. T. SPURR, (Principal Research Officers, Ferodo Limited), published by Chapman and Hall, London, and Barnes and Noble, New York, 1967, 292 pp.; 50 s. (price in U.K.). This book was primarily written for design engineers, but the phenomenon of braking is of such general interest that it should find a much broader range of readers. A discussion of factors important in the deceleration of a vehicle serves as a starting point. The following two chapters on the actuating system and an analysis of brakes deal iv&r alia with the friction sensitivity of brakes and the theory of squeal. Wear, rz (1968) 380-352
