Cr2O3 Powder

$23.00

Chromium oxide produce the most chemically inert and wear resistant thermal spray coating of all the oxides within the Oerlikon Metco product line. Typically, these materials are chosen for applications where a hard, wear resistant and chemically inert surface is needed. The coatings can be used at service temperatures of 540 °C (1000 °F) or higher.

Description

Excellent coatings are achieved using the atmospheric plasma process. Addition of titanium oxide in some of these products results in coatings with improved cohesive strength and higher fracture toughness. Compared to zirconia-based ceramic coatings, chromium oxide coatings have higher microhardness and macrohardness; however, they exhibit higher thermal conductivity and are, therefore, not as thermally insulative.
