【Abstract】 This paper deals with the anti-corrosive nitriding process for the large shaft made of 34CrNi3Mo steel. Using proper nitriding equipment and process, a 30μm depth white layer containing fine and non-brittle single ε-phase may be obtained. The electro-chemical corrosion of nitriding specimen and the observation of practical parts were denoted that, the corrosion resistance is favourable. The nitrided shaft has been assembled and used in practice.更多还原
