Quality in a class of its own - economical & reproducible
AHC stands for the development, production and finishing of functional and highly durable surface designs of metallic materials. For decades, we have been the high-performance partner for the automotive industry and have experience of thousands of joint projects in this industry.
One billion components
Every day, several million parts are coated in our factories. Each year, AHC functionally refines a billion components. We are a strategic partner for the international automotive industry in the new development and reliable just-in-time production of high-quality, innovative surface designs. There is hardly an automobile in the world that does not contain a component coated by the AHC Group.
More options in downsizing & lightweight construction
Improved material properties are in demand
Smaller, lighter, less friction. The downsizing requirements for engine components are challenging and always require higher-quality components. AHC's coating systems play to their full strengths here and give the components the required material properties.
More options for reducing displacement
For example, for designers, through the use of turbochargers or compressors. DURNI-COAT® coated compressor wheels have a significantly higher thermo-mechanical load capacity. This is particularly effective when feeding exhaust gases to the compressor side of a turbocharger, as here the finest particles place excessive stress on the compressor wheel at immense speeds.
Control piston for CO2-reducing hydraulic systems
Particularly small gap dimensions are required here in order to enable lower hydraulic pressures and lower oil circulation volumes. As a result, smaller, lower-cost oil pumps can be built, resulting in reduced CO2 emissions. The control edges of the pistons are electroless nickel-plated using the DURNI-COAT® process. The coating is then machined to size. The coating reduces the risk of "piston seizures" due to foreign particles and improves the tribological properties of the pistons.
