The coa ings were charac erized wi h X- ray diffrac ion, energy dispersive spec roscopy elec ron microscopy, and conven ional mechanical probes. The resul s show ha he face- cen ered cubic- phased TiN domi- na es in he fairly compac , uniform, gradien coa ings, wi h T iAlZrCr alloy as he ransi ion layer, and ha he gradien coa ing significan ly improved he mechanical pro
