Abstract
A surface of a work piece is provided with an adherent, thin but uniform, coating layer of a chemical compound by forming the chemical compound by explosive conversion of a substance into a gaseous state and in one working process, and applying the resulting compound to such surface by means of a surge current discharge.
Claims9
Process of forming and applying a layer of a reaction product to a surface of a base, which comprises:
- bringing together at least two chemically different components, one of which is an electric conductor, and the other is a solid or liquid in imediate contact therewith, in immediate proximity to said base, and
- explosively forming a reaction product of said components by effecting a surge current discharge through said conductor, thereby generating a plasma state in which said formed reaction product is hurled against the surface of said base.
