The perfect thermal spraying for crankcases
With the development of the G500TS thermal spraying system, GROB meets the requirements of modern engine development and offers customers in the automotive industry complete manufacturing lines for the production of aluminum crankcases with thermally sprayed cylinder bore surfaces.
The G500TS production cell offers convincingly simple integration into the flexible GROB system solutions for combustion engines and covers the cylinder bore surface with a wafer-thin steel coating as part of the overall process. Top notch technology for your efficient manufacturing facility!
Advantages
Reduced engine weight
High wear resistance
Good friction characteristics between piston ring and cylinder bore surface
Potential for high charging levels
Less blow-by
High resistance to aggressive fuels
Favorable cost-benefit ratio
Reduced fuel consumption
GROB thermal spraying methods
Wire method
The GROB wire method gives you a favorable thermal spraying material, a high degree of process reliability and simple material conveying: A transport gas centrifuges fine droplets of a molten steel wire onto the cylinder bore surface, where they instantly solidify into a wafer thin layer.
Powder method
The GROB powder method offers advantages such as high flexibility of the material and a tried and proven process: A powder is fused by means of electrical current and a plasma gas. Unlike the wire method, a powder conveyor is required here.
