Nickel coating on zinc alloy is quite promising for the achievement of an additional wear improvement in corrosive environment. To investigate this point, block-on-ring tests were carried out. 5x5x20 mm3 blocks were obtained from real locking components, made of ZP5 EN 12844 and coated by Zn/Cu1Ni5s ISO 1458. As counter material, an AISI 304 with a 40 mm diameter cylindrical geometry was used. Two load levels (5 and 15 N) and three coating thickness levels (low: 5 to 10 μm; medium: 10 to 15 μm; high: 15 to 20 μm) were considered. The sliding distance was set to 500 m and three replications per test condition were run as a total. The results, in terms of volume loss due to wear, were processed using the statistical tool of two-way ANOVA and Fisher-test. It was assessed that the wear rate is strongly affected by the applied load.

Abstract
Nickel coating on zinc alloy is quite promising for the achievement of an additional wear improvement in corrosive environment. To investigate this point, block-on-ring tests were carried out. 5x5x20 mm3 blocks were obtained from real locking components, made of ZP5 EN 12844 and coated by Zn/Cu1Ni5s ISO 1458. As counter material, an AISI 304 with a 40 mm diameter cylindrical geometry was used. Two load levels (5 and 15 N) and three coating thickness levels (low: 5 to 10 μm; medium: 10 to 15 μm; high: 15 to 20 μm) were considered. The sliding distance was set to 500 m and three replications per test condition were run as a total. The results, in terms of volume loss due to wear, were processed using the statistical tool of two-way ANOVA and Fisher-test. It was assessed that the wear rate is strongly affected by the applied load.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
