Al-Si EXCELLENT HIGH ELASTICITY AND WEAR RESISTANCE HYPER-EUTECTIC AL-SI ALLOY

摘要

The present invention relates to the hypereutectic aluminium-silicon alloys with excellent elasticity and excellent wear resistance, and relate more specifically to the hypereutectic aluminium-silicon alloys and excellent wear resistance with excellent elasticity for including: the about 13-21 wt% of silicon (Si); The about 1-5 wt% of nickel (Ni); The about 4-5 wt% of titanium (Ti); About the 0. of boron (B)7-1 wt% ; Remainder comprising the Al and inevitable impurity of 100 wt% relative to hypereutectic aluminium-silicon alloys. Have the effect of that the hypereutectic aluminium-silicon alloys of excellent elasticity and excellent wear resistance obtain the limitation for overcoming the elasticity of hypereutectic aluminium-silicon alloys, improve the wearability etc. of coating, use an other reinforced phase, such as Al_3Ni stages for being generated by the nickel (Ni) that can strengthen etc., it improves and becomes the worse property, such as TiAlSi of substance etc. by a three tunnel stages.
