...composition would be as follows: C 0.2–0.3% Mn 0.4–0.6% Al 0.9–1.4% Cr 0.9–1.4% Mo 0.15–0.25% [Images to demonstrate 'Plasma nitriding/carburising' - see article ] Design: Both processes produce little distortion of components, and hence minimise the need for post-treatment machining or grinding. Due to the lower temperatures employed, plasma nitriding gives the...
