Production of highly porous fractal coatings by the plasma-explosion method

Experiments on deceleration of a dense metal plasma obtained under explosive loading of porous specimens have shown that a highly porous coating is formed on the target surface. The coating has a vortex structure; finely dispersed fractal filaments are located on the surface of the vortices. The sprayed surface consists of the recrystallized material of the porous specimen with small admixtures of the target material. In the case of deceleration of a multicomponent plasma, the coating has an analogous structure and consists of the specimen components and target material, which are uniformly distributed over the surface.
