To provide a surface coating method by which a dense surface coating film having a sufficient thickness can be formed on the surface of a base material to be coated by using a coating material different from the base material, and the surface coating material.
The surface coating method has a process comprising allowing a powder 2 of the coating material to exist on the surface of a base material 1 to be coated, then rotating a pressure-contact body 4 while pressing the tip contact part 5 of the pressure-contact body 4 onto the powder 2 toward the surface of the base material 1 to be coated with a set load, at the same time, heating at least an area applied with the load of the surface of the base material 1 and the powder 2 of the coating material to a prescribed temperature or higher, and forming an initial coating film 3 on the surface of the base material 1 by moving the pressure-contact body 4 along the surface of the base material 1, and a heating and diffusing process for finishing a surface coating film 30 by diffusing the components of the coating material into the base material 1 from the initial coating film 3 through the coating interface by heating the base material 1 or the like in a non-oxidizing atmosphere.
