We study the corrosion and tribocorrosion behaviors of hard alloys of the VN20 + Cr3C2 and VN20 + VC systems in solutions based on 3% NaCl with different рН values. In alkali media, the corrosion currents and friction coefficients are lower than in acid media, which is explained by the inertness of nickel. The VN20 + 1 wt.% Cr3C2 alloy has the highest corrosion and tribocorrosion characteristics.

铬和钒碳化物合金化对 WC-Ni 系硬质合金腐蚀和摩擦腐蚀特性的影响

我们研究了 VN20 + Cr3C2 和 VN20 + VC 系统的硬质合金在基于 3% NaCl 的溶液中具有不同的 рН 值的腐蚀和摩擦腐蚀行为。在碱性介质中，腐蚀电流和摩擦系数比在酸性介质中要低，这可以用镍的惰性来解释。VN20 + 1 wt.% Cr3C2 合金具有最高的腐蚀和摩擦腐蚀特性。
