In：The preparation technology of the rub resistance metal coating is carried out according to the following steps：
Step 1：Metallic element carbon, sodium, aluminium, silicon, calcium, cobalt, nickel, manganese, niobium, molybdenum, neodymium, promethium and iron are put in smelting furnace and are heated,
By temperature with the speed constant-speed heating of 20-25 DEG C/min to 600-620 DEG C, 3-5 hours are then incubated, then again with 7-9 DEG C/s
Speed be heated to 1400-1450 DEG C, be incubated 1-3 hours；
Step 2：After completing step 1, samarium, gadolinium, terbium element are then added in smelting furnace, stirred with the speed of 200-300r/min
30-45min, is then incubated 8-10 hours, and the process whole process in stirring is passed through helium as protective gas, is then air cooled to
Room temperature；
Step 3：Metallic object will be obtained after cooling down in step 2 and is put into crushing in ball mill, be first heated to 300-400 DEG C, be incubated 30-
45min, then proceeds by crushing, crosses 100 mesh numbers and crosses 200 mesh numbers, respectively obtains metal dust A and metal dust B；
Step 4：First metal dust A is uniformly sprayed to inboard wall of base, thickness is 0.05-0.08mm, is then heated to 200-
280 DEG C, 1-3 hours are incubated, then again metal dust B are uniformly sprayed to inboard wall of base, thickness is 0.06-0.10mm, so
Afterwards 620-650 DEG C is heated to the speed of 5-8 DEG C/s, is incubated 1-3 hours, it is cold with the speed of 12-15 DEG C/s then using oil cooling
But to room temperature, finally with the speed constant-speed heating of 3-5 DEG C/s to 700-800 DEG C, 3-5 hours are incubated, are then air cooled to room temperature i.e.
Can.
