Examples relating to coating an alloy substrate are described. For example, techniques for treating a surface of the alloy substrate for coating the alloy substrate with an exterior coat include providing an alloy substrate of a die-casted metal alloy, the alloy substrate having a surface with multiple pores, and applying an electrically conductive layer on the surface of the alloy substrate. The electrically conductive surface is composed of metal particles and electrically conductive polymers, and the electrically conductive layer is applied such that the metal particles fill the multiple pores on the surface of the alloy substrate. Thereafter, an oxidation process is performed on the surface to form an oxidation layer over the surface. The oxidation layer provides for adhesion of the surface with the exterior coat.

A component (10) for a motor vehicle has a main body (12) produced from a magnesium material. The main body (12) has a visible surface (14) with an arithmetic mean roughness Ra of 1 to 40 m. A clear lacquer coating (40) is disposed on the visible surface (14) of the main body (12) and has a layer thickness of at most 60 m. The clear lacquer coating (40) is applied so that the surface structure (15) of the main body (12) that is disposed below the clear lacquer coating (40) is distinguishable in a visible and haptic manner.

A method and system are disclosed for impregnating a porosity of a part with sealant without immersing the part in sealant or using a known batch process. At least one fill source and at least one drain source are connected to the part, wherein the fill source and drain source are each in communication with a porosity of the part. In one aspect a vacuum is applied through the fill source and through the porosity, and sealant is then released into the porosity. Pressure can be applied to the porosity after the sealant is released into the porosity to assist in pushing the sealant into the porosity. Excess uncured sealant can be removed by injecting water into the porosity and then drawing out the water with the excess sealant. Heated water may be introduced into the porosity to cure the sealant if the sealant requires heat to cure.
