摘要
采用不同的熔炼温度和浇注温度进行了汽车缸盖用新型铝合金的铸造,并进行了力学性能和磨损性能的测试与分析。结果表明,随熔炼温度从700℃升高到760℃,浇注温度从690℃升高到740℃,试样的抗拉强度和耐磨损性能均先提高后下降。汽车缸盖用新型铝合金的工艺优选为:750℃熔炼和720℃浇注。
A new type of aluminum alloy for automobile cylinder head was cast by using different melting temperatures and pouring temperatures.And the mechanical properties and wear properties were tested and analyzed.The results show that with the increase of the melting temperature from 700℃ to 760℃,the increase of pouring temperature from 690℃ to 740℃, the tensile strengh and wear properties of the samples firstly increase and then decrease.The optimized technology of new aluminum alloy for automobile cylinder head is melting at 750℃ and pouring at 720℃.
