Step (1): carbon, aluminium, silicon, vanadium, nickel, chromium, scandium, molybdenum, boron, tungsten, titanium, barium and ferro element are put into smelting furnace, then after furnace temperature being risen to 550-560 DEG C, insulation 1-3 hour, then temperature is risen to 1120-1130 DEG C, put into lanthanum, neodymium, promethium, lutetium, terbium rare earth element, stir, insulation 3-5 hour, then air cooling is to 350-360 DEG C, then air cooling is to room temperature;
Step (2): through the refining of LF stove, temperature is increased to 1380-1390 DEG C, and puts into auxiliary agent, insulation 3-5h, omnidistance nitrogen blowing stirs, and then cools the temperature to as 670-680 DEG C; Then water-cooled is cooled to 270-280 DEG C with the speed of 7-10 DEG C/s, and then air cooling is to room temperature;
Step (3): the metal that step (2) obtains is put into ball mill, temperature is increased to 620-650 DEG C, insulation 1-3 hour, then start ball mill abrasive dust, then temperature is increased to 820-830 DEG C, insulation 1-2 hour, be reduced to 450-460 DEG C, pulverize, cross 200 mesh sieves, obtain powder particle B;
Step (4): it is 0.5-0.8mm that the powder particle B in step (3) is sprayed into hydro-cylinder surface thickness, is then heated to 880-890 DEG C, insulation 1-2 hour, cool the temperature to 420-450 DEG C again, insulation 1-2 hour, air cooling to room temperature, then clean surface.
