Imagineering Finishing Technologies was approached by a global automotive component supplier to produce a phosphate coating for engine components so that they could withstand the rigorous environment of SAE oil qualification. In order for accurate results during the qualification process, it was imperative that the engine components were consistently coated so that the wear of the components would be due to the oil and not the components.
Using a manganese phosphate coating on specially-made forged steel components, the coating reduced friction, held lubrication on the surface, prevented corrosion, and created an oil-absorptive surface. We tested the components for coating weight, coating structure analysis, and engine wear as well as performing dimensional inspections. Our tolerances on this project were .0002″ and we met proprietary automotive and SAE specifications.
With over 50 years of metal finishing experience, Imagineering has the ability to handle intricate and unique jobs. Please see the table below for and outline of this phosphate coating project or contact us for additional information.
