About Course
An introduction to surface treatment; why is surface treatment needed, how is it applied, and which different types are available? The surface treatment contains features that are essential for the bolted joint function and lifespan.
Requirements are incredibly high – despite this fact, the coating layers are thinner than a human hair.
