Recently, it is necessary fir surface materials to be low cost and to keep well endurable and wear in machinery field. Since most good materials with endurance and wear are expensive, they are being studied hard to modify to surface materials with endurance and wear, which overlay with the surface membrane completely. One of them is PTA(Plasma Transferred Arc Overlaying Process) method, which gets into the spotlight. It is thought to be an optimum method, since this method of overlays properly materials with about 3∼5cm surface membrane. It is necessity for the modified materials with endurance and wear to improve within the agricultural environment. Therefore, this research was used the PTA method to endure and wear a material. This method proved to be a reliable method for overlaying the membrane on the materials of an economical agricultural machinery.
