Abstract: PURPOSE: A molybdenum spray-coating method for a valve lift is provided to obtain low-frictional properties and heat resistance by spray-coating cheap molybdenum instead of an existing DLC coating method, thereby improving fuel efficiency and reducing raw costs. CONSTITUTION: A molybdenum spray-coating method for a valve lift includes the following steps of: blasting particles of sand on the surface of a target object (13); forming a molybdenum spray-coating layer (11) on the surface of the target object with a spray-coating method by utilizing molybdenum as a spraying material; and polishing the surface of the target object on which the coating layer is formed. The spray-coating layer has air-pores, and oil flows into the air-pores in an oil-rubbing process so that lubrication is increased.
