Wear behavior, Stainless steel, Medium-carbon steel, Block on ring


This research study investigated the behavior of wear during block-on-ring sliding contact according to ASTM G77 standard test. The testing was performed at a rotational speed of 530 rpm, for a duration of 20 minutes, and with a testing load of 600 grams. The response variable studied was the weight loss of the test specimen. The test specimen was a non-corrosive stainless steel 316 of size 16 x 40 x 4 mm, and the ring was made of S45C grad Medium-carbon steel coated with two types of materials: Titanium Nitride (TiN) and Titanium Carbonitride (TiCN). The size of the ring was OD26 x ID16 x 20 mm. The study found that the test specimen had the highest wear when sliding against the ring coated with Titanium Nitride, as evidenced by the weight loss values of both the test specimen and the ring (0.03655 and 0.10598 grams, respectively). On the other hand, the test specimen that slid against the ring made of carbon steel S45C had a lower wear rate, as shown by the weight loss values (0.0070 and 0.02208 grams, respectively). Lastly, the test specimen that slid against the ring coated with Titanium Carbonitride had the least wear due to its resistance to wear, as seen from the weight loss values (0.01804 and 0.0016 grams, respectively). This test demonstrated that Titanium Carbonitride coating had the highest wear resistance.
