Pre-oxidation technology for improving wind power gear gas carburizing efficiency

The invention relates to a pre-oxidation technology for improving wind power gear gas carburizing efficiency. The pre-oxidation technology includes the following steps that carburizing steel is slicedinto a gear-shaped sample; the sample is subjected to thermal refining; the sample is subjected to ultrasonic cleaning and drying after grinding; the sample is placed in a program control box type electric stove and is subjected to the pre-oxidation treatment; and the sample is placed into a gas carburizing multipurpose stove, and is subjected to carburizing, quenching and tempering treatment. The pre-oxidation technology has the beneficial effects that the pre-oxidation treatment is carried out before the gas carburizing, an oxidation film layer is formed on the sample surface, wettability of the sample surface is increased and the pre-oxidation treatment is beneficial for absorbing activated carbon atoms; the oxidation film is preferentially restored during the process of gas carburizing, through the defect of existing a plurality of holes on the sample surface, permeating of the activated carbon atoms into the base body, and a quick channel is provided for diffusing the carbon atoms; and gas carburizing efficiency is greatly improved, carburizing time is greatly shortened in the condition of reaching the same layer depth of the carburizing and the energy is saved.
