The preparation method of antioxidant wear-resistant composite coating 120 is using spraying equipment, by first coating 121, second coating 122 and third coating 123 dusty material be coated in matrix 110 on, comprising the following steps:
110 surface shape of matrix will be sprayed to according to the alloy powder that weight percentage of each component content obtains shown in table one At the first coating 121 with a thickness of 1~20 μm;
First coating will be sprayed to according to the metal ceramic powder that weight percentage of each component content obtains shown in table two The second coating 122 with a thickness of 10~30 μm is formed on 121;
Second coating will be sprayed to according to the metal ceramic powder that weight percentage of each component content obtains shown in table three The third coating 123 with a thickness of 10~30 μm is formed on 122.
The spraying to matrix 110 is completed according to above-mentioned steps, obtains the furnace roller with antioxidant wear-resistant composite coating 120 10.The technical parameter of the furnace roller of furnace roller 10 and direct coated ceramic material that embodiment 1-8 is obtained is as shown in Table 4:
Table four
Wherein, the antioxygenic property of coating can be measured by 1100 DEG C of 48h oxidation weight gains, and the four sides of test block is applied There is the coating material of each embodiment, then this test block is put into chamber type electric resistance furnace, is heated to keep the temperature 48h at 1100 DEG C, take It weighs after cooling down out, the weight gain of unit of account chronomere area coating;The unit time weight gain of unit area coating is fewer, resists Oxidation susceptibility is stronger, on the contrary then weaker.
The abrasion loss amount of coating can be calculated by the abrasion loss under 900 DEG C of high temperature, be tested by high temperature friction and wear Machine carries out wear test to the test block of the above-mentioned coating material for being coated with each embodiment respectively, in 900 DEG C of test temperature, revolving speed Under 150rpm, test pressure 15N, stroke 15mm is tested, is tested 5 minutes, the weight of the test block before and after wear test, meter are weighed Calculate abrasion loss weight;Abrasion loss weight is bigger, and wear resistance is poorer.
The thermal shock resistance properties of coating is the heating water cooling number for making coating shedding by measuring, and is coated with each embodiment for above-mentioned Coating material test block be heated to 1200 DEG C keep the temperature 20 minutes, cooled down into the water after taking-up, then observe coating shedding feelings Condition;Repeat-heating water cooling operation, until coating shedding area is more than the 2% of the coating gross area;Heating water cooling before coating shedding Number is more, and thermal shock resistance is better, on the contrary then poorer.
The bond strength of coating is then to be tested to obtain by tensile sample, and the coating material of each embodiment is sprayed to Tensile sample is made by adhesive bond in mating plate end face;Extension test is carried out using omnipotent mechanics machine, records coating Maximum load when falling off, maximum load value is bigger, then bond strength is bigger.
Although can be seen that the furnace roller of direct coated ceramic material in the result table four obtained by above-mentioned comparative test Antioxygenic property is preferable, but wear resistance, thermal shock resistance and bond strength are very poor;And it is provided by the invention anti-oxidant resistance to The antioxygenic property for grinding composite coating is suitable with pure ceramic coating, but wear resistance, thermal shock resistance and bond strength are obviously excellent In pure ceramic coating.
Embodiment in the present invention is only used for that the present invention will be described, and is not construed as limiting the scope of claims limitation, Other substantially equivalent substitutions that those skilled in that art are contemplated that, all fall in the scope of protection of the present invention.
