Traditional oil-bearing raw materials by mechanical mixing iron and bronze powder, inevitably producing ingredient and microstructure segregation, resulting in uneven performance and the hard phase, leading to increased running noise bearing and shorten life. In order to overcome the traditional mechanical mixing powder disadvantage fundamentally effective solution to the chemical composition of oil-bearing products and tissue segregation problem. Taking iron as the matrix, the use of chemical plating and displacement plating two methods were implemented in the quantitative iron powder coated
