Sartwell, B D; Kant, R A

Chromium oxide coatings were deposited using the IBAD technique at two different deposition rates and two different thicknesses onto single crystal silicon substrates, with their friction and wear behavior being evaluated in sliding against a silicon nitride ball. Load of 6-mm-diameter ball on the coated substrate was either 1 or 2 N. For a 0.5-micrometer-thick Cr[sub 2]O[sub 3] coating, wear rates were high, with the coating being removed after only 50 passes on the tribotester. For a 2.0-micrometer-thick coating, wear rates were extremely low such that after 500 passes virtually no film removal could be detected on a profilometer.
