Adhesion and hardness of platinum coatings electrodeposited from molten salts.
Walters-RP; Lynch-MJ; Flinn-DR
Plating Surf Finish 1983 May; 70(5):91-95
Utilizing a direct pull solder method, the adhesion of platinum coatings to tzm and fe10cr substrates was determined. The average fracture value was 331 mpa (48,000 lb/in), with fracture occurring in the substrate or in some combination of the substrate, coating, and solder, but not at the deposit-substrate interface, indicating that the true adhesion of the coatings is greater than the measured fracture values. Cross-sectional hardness values were dependent on the average grain width, with hardness values ranging from 52 to 120 hk25 at 35 and 8 um, respectively, from the substrate-coating interface.
