The design of composite materials for wear resistant service aims at com- bining two or more materials in such a way as to achieve unique and useful properties not generally available in any single homogeneous material. Properties and applications are presented of what might be described as a new generation of wear resistant materials, namely, metallic and part- metallic composites suitable for use in the high abrasion/moderate impact environment encountered in the crushing and screening of ore. Significant cost performance benefit can result from the use of such materials and several specific case histories are discussed._x000D_
Some promising new developments, utilis- inn white iron and rubber, as yet in the field testing stage, are reviewed._x000D_
Further comments are offered foreshadow- ing new composite developments, as yet untried but which appear to h,uve merit.
