Brass coating was applied to AISI 410 stainless steel substrate using high power laser in a Laser Engineered Net Shaping (LENS™) system. Laser deposition resulted in a diffused and sound interface between metallurgically incompatible brass coating and AISI 410 stainless steel substrate. The thermal conductivity of AISI 410 steel increased from 27 W/mK to a maximum of 37 W/mK depending on the coating thickness, almost a 50% gain. The absence of sharp interface between the coating and the substrate, as a result of laser processing, resulted in low interfacial thermal contact resistance. Based on thermal performance tests, the brass coating found to enhance not only the heat transfer by conduction but also the convective heat transfer rate. These results show that novel and efficient feature based coatings can be created by exploiting the capabilities of laser based coating approach and advanced manufacturing technologies for various industrial applications.
