We must reduce consumption of energy and materials in order to hand down an ample supply to future generation since natural resources in the world are diminishing continuously. This principle should also be applied to the repair and maintenance of industrial machines. The use of high performance coatings on machine components improves their performance as well as increases their service lives. Application of coatings that resist wear, corrosion, heat, etc., using low heat input coating techniques reduce energy consumption and save materials. The use of high performance reduces not only downtime but also stockpiling of spare parts, and leads to improved productivity.
