The application of coatings to engine components ensures greater resistance to high temperatures, a reduction in loss of power due to friction, an increase in contact pressures and a reduction of wear.
Lafer has developed a complete range of very high-performance surface coatings, to provide each engine component with the best coating for its specific function.
For many years, the R&D department has focused on perfecting a production process that has allowed Lafer to offer customers a 360° service.
Lafer coatings improve performance and ensure an increase in the service life of components by reducing friction coefficients, consequently reducing the need for lubricants and improving their resistance, duration and reliability.
Lafer has developed a series of customized processes to produce results that can surpass conventional coatings.
The entire range of services is carried out in-house in the surface engineering department. For each stage of the process, systems with various capacities give us flexibility to process both individual pieces and large series components, while always guaranteeing the maximum possible quality and the repeatability of results.
