Experimental Determination of the Hardness Curves in Deep Carburizing Heat Treatment
Journal Title: RECENT - Year 2013, Vol 14, Issue 40
Abstract
Was achieved an experimental research of influence of carburizing time on hardness and depth. The variation of the carbon content depth, which determines the appearance of the curve of the carbon content (carbon profiles), is revealed for SAE 3310. Determining hardness curves allows setting optimal parameters for carburizing process, eliminating hyper-carburization of the outer layer, and allows a carburizing depth up to 10 mm. After quenching, was necessary to find a solution to reduce the amount of carbon in the normal. This was done by applying an annealing diffusion treatment after carburizing into the atmosphere of carbon potential decreased. The hardness curve demonstrates the necessity of the proposed solution.
