Light metal part activation for casting with another light metal part |
摘要 |
A cylinder-liner blank which preferably consists of a hypereutectic aluminum/silicon alloy and is cast into a crankcase. A special surface treatment achieves better material bonding of the liner in the crankcase. The blank has a roughness of 30 to 60 mu m on its outside, in the form of pyramid-like or lancet-like protruding material scabs or material accumulations. To obtain this roughness, the surface is blasted with particles which are broken so as to have sharp edges and consist of a brittle hard material, preferably high-grade corundum, with an average grain size of about 70 mu m. A fine fraction is formed and is continuously separated off. The average grain size is maintained by adding new particles.
