A back-to-back gear test rig is used to perform the new test method. We tested the low-friction coatings: a-C:H:W and MoS 2 /Ti deposited on the test gears. The best resistance to scuffing/scoring is obtained when both gears are a-C:H:W-coated. …
WebDamage from scuffing Micropitting With the FVA-Workbench, the local micropitting resistance can be calculated according to ISO TR 15144. Intermediate results such as the local lubricant film thickness and sliding speed are also output for better evaluation of the calculation results.
