Description
Qianjie Wang and four co-authors tune the laser settings for coating steel dies with a hard cobalt alloy. Their 2024 study uses laser cladding to lay Stellite 12 onto H13 steel, the stuff of aluminum extrusion dies that crack in service. The goal is a harder, wear-resistant skin.
Coatings were laid at several laser power levels and checked under microscopes and hardness testers. As power rose, surface quality improved while more base steel mixed into the coat. Hardness and wear resistance first rose, then fell past a sweet spot. The best mix sat at twenty-two hundred watts with set scan and feed rates. The authors give die makers a tested recipe for longer-lasting tool surfaces.
