Tribological Behavior of Ni-Based WC-Co Coatings Deposited via Spray and Fuse Technique Varying the Oxygen Flow

Table 2

Average values of surface microhardness of MetaCeram coatings deposited at different oxygen fluxes.

MetaCeram samples	Average microhardness (MPa)	Thickness (µm)
Steel ball	8218 ± 94,31
Substrate	347.48 ± 54	-
MetaCeram (theoretical value)	10850	-
(11.04 SCFH)	9448.09 ± 32.15	228.41 ± 6.42
(12.88 SCFH)	10470.64 ± 61.23	230.53 ± 4.14
(14.72 SCFH)	10092.27 ± 12.95	270.14 ± 9.03
(16.56 SCFH)	9010.88 ± 67.65	250.16 ± 2.97

The microhardness values summarized in Table 2 were made on the surface of the coatings since other values of the microhardness were made on the transversal section.
