Development of AICrN/TiAIN/AIN/TiN nano-coatings for cutting tools

This work examines the frictional and wear behaviour of AlCrN, TiN, TiAlN single­layer coatings, and TiAlN/AlCrN, AlN/TiN nano-multilayer coatings in dry sliding. Comparative studies on the coatings sliding in air and vacuum environment at different speeds provided important insight on the effect of...
