Automotive cast, engine and gear-box parts are made of Magnesium since many Years. In the past Years a lot of research has been done to increase the strength and creep resistance for casting parts. Magnesium is also in use for chassis parts like doors. However the low corrosion resistance is from concern for chassis parts made of Magnesium. For applications in a non corrosive environment like dash boards, steering housings or seat frames it is a material of choice.
Engine housing made via high pressure die castings could be reinforced locally with ceramic performs. From interest are areas like the cylinder liner and bearings of the housing and the bearing cap/bedplate.
· Because of the large increase in strength it is for many applications not necessary to use an expensive matrix alloy, e. g. AZ41, AZ91 instead of rare-earth element containing Magnesium alloys.
