Embodiment 1
[0011] A method for surface treatment of steel parts, comprising the steps of:
[0012] (1) A steel sample with a size of 10*10*5mm is taken as the base material, and block pure aluminum is used as the source material;
[0013] (2) The steel sample was polished with sandpaper for multiple passes, and then mechanically polished with 0.5 μm diamond spray polishing agent, then ultrasonically cleaned in acetone, alcohol, and deionized water for 10 minutes, dried, and packaged for use;
[0014] (3) Carry out aluminizing treatment with a double-layer glow plasma metal infiltration vacuum furnace, use a stainless steel cylinder as an auxiliary cathode, and place the base material and block pure aluminum in the auxiliary cathode;
[0015] (4) Start surface treatment: process parameters are frequency 55Hz, pole spacing 15mm, holding temperature 800°C, holding time 2h, source voltage 400V, cathode voltage 250V, after treatment the sample is cooled to room temperature with the furnace. ...
