Process for coating an aluminium alloy device of an internal combustion engine with silicon |
摘要 |
The method concerns coating of an aluminium-alloy component (2) of an internal combustion engine with silicon by means of a high-energy beam, in particular, a laser beam. By means of an appropriate powder feed unit (similar to the equipment used in plasma spraying installations) in combination with a high-energy beam (10), an aluminium-silicon powder is transformed into a liquid phase, and is applied to the component surface (2') in the form of fine droplets to form a layer (9). The finely dispersed silicon is released during subsequent solidification of the layer. |
