发明名称 LIGHT-METAL CYLINDER BLOCK AS WELL AS METHODS OF AND APPARATUS FOR MANUFACTURING SAME
摘要 A light metal cylinder block, having hard cylinder running surface layers of aluminum-silicon alloy containing finely disper round primary silicon particles, is new. A light metal cylinder block has cylinder running faces comprising a surface layer which has a hardness of NOTLESS 160 HV which consists of 10-14% Al-Si eutectic, 5-20% uniformly dispersed round primary silicon precipitate particles of 1-10 mu average diameter and balance pure Al phase. Independent claims are also included for the following: (i) production of the above light metal cylinder block by gravity, pressure or pressure die casting and then surface treatment with a laser beam parallel to a powder jet, the laser beam being pas with a width of≥2 mm over the light metal matrix surface and the powder being heated to the melting temperature and inwardl diffused in 0.1-0.5 sec. at the laser beam incidence point; and (ii) equipment for carrying out the above process.
