Additive Manufacturing of cBN-Copper Grinding Wheel Coatings via High Pressure Cold Gas Spraying
Abstract This study investigates the cold gas spraying (CGS) process as an innovative approach for fabricating cBN-copper composite coatings. CGS, a low-temperature thermal spray and additive manufacturing process, prevents thermal degradation of sensitive materials such as cBN and ensures a dense coating with a high bond strength. The research focuses on key parameters such as primary gas temperature and pressure as well as the ratio of cBN to copper, analyzing their effects on coating performance.
