Abstract
Plasma surface modification is a unique method to modify and optimize the surface properties of materials and industrial components. One of the advantages of this technology is that the surface properties such as hardness, corrosion resistance, and other tribological, chemical, and physical properties can be selectively modified without affecting the bulk attributes of the materials. For example, artificial heart valves can be treated to become more biocompatible without compromising their mechanical sturdiness and the surfaces of oil pumps can be made more wear resistant without changing their critical dimensions. The technology can be applied in many fields including microelectronics, metallurgy, polymer engineering, biomedical engineering, etc. Prof Chu and his research team can provide consulting services ranging from process design, plasma equipment design, to equipment production (plasma equipment and power supplies).
