Iron-based sintered sulfidic material and method for its production
By dissolving sulfur in lubricating oil and immersing sintered materials at high temperatures to generate Cu2S, the problem of uneven sulfidation in complex-shaped iron-based sintered materials is solved, achieving uniform sulfidation and low-cost production, and improving the friction-reducing properties and stability of the materials.

AI Technical Summary
Existing technologies struggle to achieve uniform vulcanization on complex-shaped iron-based sintered materials such as irregular or curved surfaces, resulting in unsatisfactory friction reduction effects. Furthermore, the vulcanization process is inefficient and costly, particularly for bushing materials where vulcanization is uneven on the surface.
By dissolving sulfur in lubricating oil and immersing sintered materials at high temperature, the sulfur reacts with copper in the pores to generate Cu2S, while simultaneously filling the lubricating oil and forming a uniform sulfide layer. This process is simplified to a one-step operation, reducing energy consumption and costs.
Uniform sulfidation was achieved on iron-based sintered materials with complex shapes, reducing the friction coefficient, decreasing process steps and energy consumption, improving sulfidation uniformity and material stability, and significantly reducing production costs.
