Method for preparing antibacterial and wear-resistant stainless steel permeation layer

The invention provides a method for preparing an antibacterial and wear-resistant stainless steel permeation layer, belongs to the technical field of stainless steel surface protective coatings, and provides a method for diffusion coating of a uniformly distributed antibacterial and wear-resistant stainless steel permeation layer on a stainless steel matrix workpiece. The reaction process is controllable. The technical scheme comprises the following steps of: 1, putting the stainless steel matrix workpiece into a double-layer metallic glow ion cementation furnace, taking a pure titanium plate as a sputtering target, argon as working gas, and nitrogen or mixed gas of nitrogen and methane as reaction gas for diffusion coating; and 2, putting the stainless steel matrix workpiece subjected to diffusion coating into a vacuumized muffle furnace, introducing oxygen to react with the permeation layer of the stainless steel matrix workpiece, controlling the heating temperature range to be between 400 and 600 DEG C, keeping the temperature for 1.5 to 2 hours, and cooling to room temperature. The method is applied to the technical field of stainless steel surface diffusion coating.
