Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the invention is described further:
The present invention prepares a kind of CrMnFeCoNi high entropy alloy coating using plasma spraying method, and sprayed on material, which is, etc. rubs
The CrMnFeCoNi globular powder (15-53 μm of crystallite dimension) of your ratio.It is using plasma spraying method that CrMnFeCoNi is spherical
On powder spray to matrix, coating with a thickness of 200 μm.
Step 1: preparing matrix and carrying out pre-treatment to it
The present invention selects 443 stainless steels as basis material, with the sand paper of different model (80#, 240#, 400#, 800#,
Matrix polish 1000#) to remove the oxide skin of matrix surface, then matrix is placed in acetone soln and is cleaned by ultrasonic 1h to obtain
Obtain clean surface.The matrix of ultrasonic cleaning is put into air dry oven and is dried.Matrix is put in sand-blasting machine and carries out sandblasting
Processing improves the caking property of matrix and coating to obtain rough surface.
Step 2: matrix is fixed on spraying frame, spray distance and spray gun and matrix distance 85mm are adjusted, it will
CrMnFeCoNi coated powder (pattern such as Fig. 1) is put into powder feeding room, and spray procedure, the i.e. running track of spray gun is arranged.
Step 3: preparing high entropy alloy coating, the main spray parameters of selection using air plasma spraying method are as follows: spray
Painting voltage is 37V, spraying current 665A, powder feeding rate 20g/min, and main gases argon pressure is 0.4Mpa, secondary gaseous hydrogen
Atmospheric pressure is 0.03Mpa, and current-carrying gas argon pressure is 0.28MPa.
