Abstract

The invention belongs to the technical field of metal heat treatment, particularly relates to a titanium alloy high-temperature solid carburizing process, and aims to solve the problem that in the prior art, a cleaning device needs to be independently arranged to clean a carburizing agent on the surface of a workpiece, so that the production cost is increased. The following scheme is provided, the process comprises the steps that a to-be-treated workpiece is fixed in a carburizing box, the carburizing box is filled with a carburizing agent, then the carburizing box is packaged and put into a heating furnace, and then the furnace temperature is increased to 800-850 DEG C and kept for a period of time, so that the temperature in the carburizing box is uniform. When a flat workpiece such as a gear needs to be subjected to solid carburizing during use, the workpiece only needs to be placed at the top ends of two telescopic rods in the carburizing box firstly, then a lower cover connected with a bottom cover in a threaded mode is used for tightly abutting against the top ends of the two telescopic rods, then suspended fixing can be formed, and then the carburizing box is filled with the carburizing agent, and the carburizing box can be pushed into the heating furnace to be heated.

Description

technical field [0001] The invention relates to the technical field of metal heat treatment, in particular to a titanium alloy high-temperature solid carburizing process. Background technique [0002] Carburizing refers to the process of infiltrating carbon atoms into the surface layer of steel, so that the workpiece of low carbon steel has the surface layer of high carbon steel, and then after quenching and low temperature tempering, the surface layer of the workpiece has high hardness and wear resistance, while The central part of the workpiece still maintains the toughness and plasticity of mild steel. Gears are key components in mechanical equipment, widely used in industrial fields such as automobiles, airplanes, tanks, and ships. Compared with similar products in other developed countries, the quality of gears in my country still has a certain gap, which is mainly reflected in the average use of gears. In terms of service life and energy consumption per unit of product...
