Surface Engineering embraces those processes which modify the surfaces of engineering components to improve their in-service performance, useful working lifetimes, aesthetic appearance or economics of production. It means 'modifying the surface' of a material or component to confer surface properties which are different from the bulk properties. The purpose may be to minimise corrosion, reduce frictional energy losses, reduce wear, act as a diffusion barrier, provide thermal insulation, exclude certain wavelengths of radiation, promote radiation electronic interactions, electrically insulate or simply improve the aesthetic appearance for the surface.
This guide concentrates on engineering applications, where the main concern is with the potential of surface damage; i.e. damage that might occur by corrosion, wear or any other aspect of the environment.
There are several possible degradation processes:
This Guide discusses the options for surface preparation and surface engineering to protect your parts against degradation. For help in selection of the most appropriate treatment for your particular problem, you should consult the Coating Selection or the Problem Solver.
The general protective process consists of four steps:
The surface engineering process can be divided into two main groups;
1. Surface Preparation Processes,
which clean and prepare component surfaces.

2. Surface Treatments, which give the material the desired properties.
There are many ways of treating metal surfaces to enhance the corrosion
resistance and/or their tribological properties. These may be grouped
into three broad categories:
