The gear shaft is flexible after assembly, and the wear resistance and seizure resistance of the parts are better than the carburized and quenched parts with the same depth and hardness. Effect of temperature and time on the depth of the layer The compound layer (white bright layer) formed by the composite heat treatment has good wear resistance, but usually the compound layer is too thin after nitrocarburizing. The effect of co-infiltration temperature and time on the depth and performance of the layer. As the temperature of the co-osmosis increases, the depth of the layer increases; the depth of the layer increases with time, and increases rapidly at the beginning, and then increases slowly.
Studies have shown that prolonging the osmosis time will loosen the compound layer, causing serious defects, and prolonging the time to increase the depth of the layer is uneconomical. Therefore, the effect of temperature on the depth of the layer should be considered in the production of glass UV light-solid machine. Under the set process conditions, the co-infiltration temperature is changed, and the element concentration of the workpiece surface remains basically unchanged. With the design layer depth and hardness index, the hardness gradient of the layer tends to be gentle. This is because after the ruthenium is treated by nitrocarburizing, the nitrogen-based compound layer and diffusion layer are obtained on the surface, and then the parts are reheated to increase the hardness curve of the layer, the diffusion speed is accelerated, and the depth of the layer is deep. Increase, hardness increases. The effect of co-infiltration temperature and time on the depth and hardness of the layer, and the decomposition of nitrogen and carbon compounds in the layer.
