The micro shot-peening treatment is performed to prepare the surface either for subsequent treatments or coatings or as a finishing, as with stainless steel surfaces.
Micro shot-peening is needed to make the surface homogeneous with the removal of about 1 micron of material and create a lightly rough surface, such as to favor the anchorage of the nickel layer with consequent improvement in terms of adherence of the deposit.
Micro shot-peening treatments are divided into three categories:
It is finally worth stressing that as a result of the different treatments, both for standard adjustment starting surfaces and for those with extrusion roughness, the degree of surface roughness, measured in Ra, as a result of Micro shot-peening is set on values of only about 1,6.
NICASIL s.r.l. has been the leader in Italy since the seventies on the sector of the electroless nickel coating. In fact, either Nicasil Process have been the most important brands of the electroless nickel coating and the metal surface treatments in Italy.
