Interparticle forces of powder particles and their coating process

Abstract

Coating is a process, by which fine particles in nano-range are connected to a powder particle material. During the initial phases of coating, surface of powder particle material is sprinkled by nano-particles and thus a lot of powder material properties can be directed and changed especially. A lot of method of surface coatings processing are discovered via commercial devices, and also there are a lot of pioneer devices working without basic knowledge of coating mechanism in laboratory background. The main advantage of the coated material is the possibility to changing the basic properties e.g. wetability, conductivity, electric and electronic properties, rheological properties, flowability, magnetic properties etc. It has been observed that only a few percentages (%W) are enough to ensure a property change and a property direction. In the paper, the coating mechanism and forces involved in coating processing are investigated and mathematical modeling of dry coating is initiated.
