Abstract

Effect on the adhesive wear of the high speed steel P6M5 (HRC 62) and tungsten carbide coating (WC – 12 % Co) was investigated in the pair with tempered steel 45 (HB 200) in air environment. Sliding speed was changed from 0.3 m/s to 1.5 m/s and the load from 30 N to 150 N. The wear was also investigated at 20 ºC, 200 ºC, 300 ºC, 400 ºC, 500 ºC and 600 ºC temperatures at constant 90 N load and various sliding speeds.
The tungsten carbide coating was deposited by high velocity oxygen fuel gun. It was found out that wear rate of the WC – 12 % Co coating decreases when sliding speed is increasing from 0.3 m/s to 1.5 m/s. Wear rate of P6M5 steel is constant in the range of speeds 0.3 – 0.5 m/s and it changes in a small interval when the sliding speed increases from 1 m/s to 1.5 m/s and the load increases from 60 N to 150 N. Higher temperature and slower sliding speed result higher wear rate of WC – 12 % Co coating. Wear rate of the high speed steel P6M5 by increasing sliding speed and temperature decreases.
Increase of the sliding speed from 0.3 m/s to 1.5 m/s or increase of test temperature from 20 ºC to 600 ºC results decrease of the friction force.
