The objectives in writing this monograph are to acquaint the reader with the reasons for extensive application of cobalt as a matrix in diamond impregnated tools and, by linking the existing theoretical knowledge with experimental observations, to try to justify the superiority of cobalt to other materials.
The technical contents of this book relate mainly to the areas of the authors research, which include:
- theoretical analysis of stone sawing process
- engineering cobalt-base matrix microstructure and properties
- industrial assessment of cobalt-containing saw segments
Additionally, the book provides guidelines for selection of metallic matrix and diamond abrasives, and describes the today's methods of saw blade manufacture. An overview is given of the cobalt powder production routes and their effect of properties. The current market availability of cobalt powders, and their substitutes, is also presented.
