FORMING SURFACE FINISHES

Forming Surface Finishes

Surface Finish is a comparatively thin component. It occurs as ‘finishing treatment’ or the outermost layer on an object. Many surface finishes are fashioned out of the objects own material, are Self finishes. On the other hand Applied finishes of the same material as the objects are made or are of completely different materials. The application of a finish over an object involves some form of material joining system. Applied finish systems are of two types. In the first case a continuous surface layer is formed by depositing one surfacing forming material, and in the other case, several surfacing components are joined to form an extensive surface layer.

 

 

Applying a Surface Finish

An applied surface finish in the form of one continuous layer, is a coating. A coating is a thin surfacing, that normally forms a surface through conversion from Liquid to Solid phase. (The liquid phase may derive from Gas or Solid phase, or a transition from high viscosity to an applicable grade viscosity.)

Applied finish of some types require joining with the base material. The joining is created mainly by Adhesion, Fusion or Mechanical holding. ‘Joining’ or surface holding is also achieved through gravity and electrical charges.

The joining as bonding or fastening occurs at two distinct levels: One, when the surfacing component attaches to the base material, and Two, when the surface components form edges to edge or ends joints. In the second case the surfacing components apparently enlarges the extent of the assembly. Edge joints of surface systems emerge or are created as per design. Though there are many surface situations (cobble stone or brick flooring) where edge to edge positions do occur, but no joining materials are used.
