Friction and wear of a plasma sprayed Al2O3-40%ZrO2-cast iron system

Autor: Jin Yuansheng, Wu Huadong, G. Barbezat, A.R. Nicoll

Publikováno v: Wear. 176:49-60

Tribological behaviour of plasma-sprayed Al2O3-40%ZrO2 ceramic coatings against three different phosphorus-containing cast irons was investigated at 200 °C and 300 °C. The seizure loads were tested and the friction coefficients recorded. Wear rates
