Matrix alloy of the present invention can be selected any commercial aluminium alloy according to service requirements.Aluminium alloy melting in the resistive heating crucible oven can be carried out under atmospheric condition.
The present invention react generation because of strengthening particle in aluminium alloy melt, fundamentally solved to add particle and the matrix alloy wettability is poor, problem such as stability difference when use easily takes place under surface reaction and the hot conditions.Because of size of particles come-up/sinking velocity little, that cause because of difference in specific gravity of generating is little, be difficult for segregation, the technology stability height of production, the poor mechanical property of 2 hours cast samples is less than 5% at interval, and this is with the stably manufactured of favourable in enormous quantities, medium and small component.It is tiny to strengthen size of particles, be evenly distributed, and the thermostability height, surface no-pollution combines well with alloy matrix aluminum.The room-temperature mechanical property of material, mechanical behavior under high temperature (300 ℃) and wear resistance significantly improve, and are particularly suitable for motorcycle, motor cylinder block, the parts of working under the high temperature conditions such as heavy duty piston, and the component that wear resistance is had relatively high expectations.
