In the past few years, a considerable increase in performance has been achieved from high speed steel and carbide metal cutting tools by the addition of hard surface coatings such as titanium nitride, silicon nitride ,titanium carbide, aluminum oxide and various combinations of the above. these… More

A radically new approach to the in situ synthesis of the constituent phases of a composite structure has enabled the production of a new wc/co material with an ultrafine microstructure. such "chemical synthetic" techniques replace the mechanical mixing and milling processes used in conventional… More

Waste paint sludge is generated in large quantities by auto-mobile, appliance, and other manufacturers and a vast majority os it is being disposed of in hjazardous land fills. past efforts to disopose of this sludge in incinerators havemet with limited success. this hazardous waste stream generation… More

A new process has been devised for the synthesis of co/wc nanocomposites powders, starting from designed molecular precursors. the process differs from conventional powder metallurgy methods in that it is a direct route for making the materials which avoids mechanical milling and handling of… More

Nitrided and/or carburized surface cases on light metals such as aluminum, magnesium, titanium, and their alloys, economically formed, would allow significant weight reduction in equipment from a simple machine to an advanced engine. Such cased material could replace steel gears, crankshafts,… More
