摘要： A method for forming a coating film on a sliding surface of a sliding member includes: a first contact step of supplying a lubricant composition containing tungsten disulfide to the sliding surface to bring the tungsten disulfide into contact with the sliding surface; and a second contact step of bringing a silane compound that is dialkoxysilane, trialkoxysilane, tetraalkoxysilane, or a polymer or a copolymer of dialkoxysilane, trialkoxysilane, and tetraalkoxysilane into contact with the sliding surface.

摘要： A windmill blade includes a blade main body and a leading edge protector. The leading edge protector includes a conductive plate covering a leading edge, and a conductive mesh member connected to the conductive plate along a blade chord direction of the windmill blade. The conductive mesh member is provided with a plurality of holes. A skin or an adhesive at least partially enters the plurality of holes, so that the leading edge protector is fixed to the skin.
