Assessment of the properties of sprayed coatings for the thermal barrier applied to the piston of internal-combustion engine

The properties of three thermal sprayed coatings (Coating①: Top coat; Al2O3, Bond coat; Ni-Cr, Coating②: Top coat; YSZ, Bond coat; CoNiCrAlY, Coating③: SUS316) were compared to select the effective sprayed coating for giving the thermal barrier to the Al alloy components of internal-combustion engin...
