【 摘 要 】

Two stainless steels namely AISI 430 and AISI 204 have been investigated for their slurry erosion resistance. The erosion tests were carried out using a pot tester at the particle impact velocity of 10.7 m/s, slurry concentration of 10%, 20% and 30% by weight and the impingement angle of 30° and 90°. To improve the slurry erosion resistance of the stainless steel AISI 430 and AISI 204, Cr3C2-25NiCr coating was deposited on that, using HVOF (High Velocity Oxy Fuel) technique. Erosion results show that Cr3C2-25NiCr coating exhibits better slurry erosion resistance than the AISI 430 and AISI 204.
