چکیده انگلیسی
ⶠThe premature failure of an aluminium injection die with a duplex surface treatment (plasma nitriding and physical vapor deposition coating) was investigated. ⶠThe origin of failure was attributed to the sulfur inclusions introduced into the surface of the tool by a sulfur-impregnated grinding stone used in the final polishing operation. ⶠThe low adhesion of the CrN coating on the sulfur inclusions led to the spalling of the coating, the exposure of the substrate material and the nucleation of cracks. ⶠNew evidence is presented on the influence of surface preparation and manufacturing processes on aluminium injection tool performance.
