[30] Where, specific Ti content of 4, 8, 12, 18 and 20 per cent were selected for group preparation experiments;
[31] A method for preparing a refractory high-entropy alloy coating comprising the steps:
[32] (1) Mix the individual powders in proportion and then vacuum ball mill the powders for 3 hours so that the powders are fully mixed uniformly;
[33] (2) Mixture of the alloy powder obtained in step (1) with anhydrous ethanol to obtain the coating material, which comprises 92% by mass of the alloy powder with 8% anhydrous ethanol,
[34] (3) The TC4 matrix is coarsely ground with 200~400 grit sandpaper to remove surface oxidation, and then cleaned by ultrasonic alcohol to remove surface stains. The mixed powder is prefabricated on the matrix with a prefabricated layer thickness of 1.0 mm and placed in a drying phase for 10 hours;
[35] (4) The dried powder is laser coated with the matrix, wherein the laser coating process parameters are: excitation power of 3700 W, scanning speed of 350 mm/min, optical shift diameter of 3 mm, off-focus volume of 20 mm, protective gas of argon, gas flow rate of 8 L/min.
[36] Example 2
[37] Based on the above described in embodiment 1, the obtained specimens were wire cut to make a sample of the molten cladding layer and the sample was etched with aqua regia for 1 min for the next step of microscopic characterization and performance testing.
[38] (1) The coating obtained in Example 1 was photographed and observed by SEM, and it was found that the coating was dense and uniform, with no obvious defects and roughly equiaxed crystal organization;
[39] The HVS-1000A microhardness tester was used to measure the microhardness of the coatings of the five components, as shown in Figure 4, with the increase in Ti content, the hardness showed an increasing trend, with the highest microhardness at 20% Ti content, with an average hardness of 1066.7 HV.
[40] (2) The coatings obtained in Example 1 were subjected to a high temperature frictid:504318 wear test at 600°C, with a friction matrix of 5 mm Si3N4, a load of 5 N, a test frequency of 0 .1
Hz and a test time of 20 min, after which the wear weight loss of each coating was obtained, as shown in Figure 5. 0.65mg, which is approximately 1/2 of the matrix;
[41] (3) The high temperature oxidation resistance of the high entropy alloy coating obtained in Example 1 was measured using a tubular resistance furnace at 800°C for 100 h.

The oxidation weight gain was less than 1/3 of that of the matrix ( 38.44 mg/(cm3)-1).
[42] Itis concluded that a refractory high-entropy alloy coating with a molar ratio of Ti: 20%,
Zr: 20%, Mo: 20%, Nb: 20% and Cr: 20% has the best overall performance of the alloy coating in all aspects.
