Pin-on-Flat Figure 6 In the pin-on-flat test the pin moves relative to a stationary flat in a reciprocating motion. The pin can be a ball a hemispherically tipped pen or a cylinder. Wear 327 Load Figure 6 Pin-on-flat wear test. Alfa Wear Test Figure 7 This test subjects samples to high pressure adhesive wear under clean lubricated conditions. A rectangular block is run against the periphery of a rotating hardened steel ring under known conditions of load sliding velocity and lubrication. The block is either a homogeneous wear resistant material or is made of steel and then coated with the wear resistant material to be tested 6 . 328 Electrodeposition Load Figure 7 Alfa wear test. Accelerated Yarnline Wear Test Figure 8 This test was designed to simulate typical conditions commonly found in textile machinery. A full-dull mil diameter nylon monofilament is drawn at 1000 yards min and 10 grams of tension through a layer of 1 micron aluminum oxide powder just inches before encountering the cylindrical test sample. CHROMIUM Chromium plating is more extensively used for wear applications than any other electrodeposited coating. Typical uses include roll surfaces shaft sleeves pistons internal combustion engine components .
