Micrography of the pin close to the interface with the spray and fuse layer. Transverse section. The fuse is conducted in high temperature and the pin was quenched and tempered after the thermal spray deposition and fuse by flame (in this case the melting of the applied layer was conducted by a oxifuel flame.
