Study of Abrasive Wear Resistant of WC Particle Reinforced Chromium White Cast Irons Matrix Composite
Wear-resistant performance of WC particle reinforced chromium white cast iron matrix composite was studied under the condition of two body wear by pin-on-disk test, and the wear-resistant performance is compared with white cast iron. The results show that with the Cr content increasing the wear-resistant performance increase, while as-cast distressing treatment. When Cr content ranges from 2% to 26%, relative wear-resistant performance ranges from 1 to 1.48, however, the relative wear-resistant performance increase over 10; with the Cr content increasing the wear-resistant performance increase slightly, while as-harden distressing treatment. When Cr content ranges from 2% to 26%, relative wear-resistant performance ranges from 1 to 1.32, while the relative wear-resistant performance up to 30.So in order to improve wear-resistant performance, using the method of prepare WC particle reinforced chromium white cast iron matrix composite is very effect.
