Embodiment 1
[0016] A thermal fatigue-resistant heavy-duty automobile engine casting material, comprising the following components by weight: 500 parts of cast iron, 80 parts of red mud, 70 parts of aluminum, 18 parts of modified aramid fiber, 12 parts of nano cobalt hydroxide, vanadium boride 6 parts, 2 parts barium strontium titanate, 1 part sodium tungstate, 2 parts cerium, 4 parts thorium, 8 parts manganese, 3 parts yttrium, 10 parts nickel;
[0017] Wherein, the red mud is dried at 420° C. for 18 minutes, and ground to a particle size of 200 nm for use.
[0018] Wherein, the modified aramid fiber is modified by a rare earth solution, and a certain amount of aramid fiber is added to a rare earth solution equivalent to 5% of its weight, and then sent into a ball mill, at a speed of 400-450 Ball mill for 30-40 minutes under the condition of rpm, take it out, and dry it by microwave.
[0019] Wherein, the rare earth solution is obtained by mixing lanthanide rare earths, ammonium nitrate ...
Embodiment 2
[0028] A thermal fatigue-resistant heavy-duty automobile engine casting material, comprising the following components by weight: 500 parts of cast iron, 90 parts of red mud, 60 parts of aluminum, 15 parts of modified aramid fiber, 15 parts of nano cobalt hydroxide, vanadium boride 5 parts, 2 parts barium strontium titanate, 2 parts sodium tungstate, 1 part cerium, 3 parts thorium, 6 parts manganese, 5 parts yttrium, 8 parts nickel;
[0029] Wherein, the red mud is dried at 450° C. for 15 minutes, and ground to a particle size of 260 nm for use.
[0030] All the same as in Example 1 except the above content.
[0031] The material in this example has been tested and found that its tensile strength is 732MPa, its elongation is 10.2%, its yield strength is 423MPa, its surface hardness is 185HBW, its toughness is 9.7J / ㎡, and its wear resistance is 22% higher than that of ordinary high manganese steel. Used in heavy-duty vehicle engines, the service life is increased by 1.5 times. ...
