摘要： A sliding spline shaft device of the present invention includes a male spline and a female spline that is fitted to the male spline in an axially slidable manner, and at least one of the splines has a surface processed layer. The surface processed layer includes an undercoat layer, an intermediate layer containing phosphate, and a topcoat layer containing solid lubricant, in this order. The undercoat layer contains iron nitride and/or iron carbide. Thus, the surface of a base material has high hardness. As a result, microscopic deformation of the sliding surface is reduced, and increase in a real contact area is suppressed, whereby stick-slip is prevented.

摘要： A process for duplex heat treatment of combined nitriding treatment and induction quenching treatment on an iron and steel material includes a chemical conversion treatment step for forming a chemical conversion film on a nitrogen compound layer formed on the iron and steel material by the nitriding treatment, after the nitriding treatment and before the induction quenching treatment. A compound layer formed on a surface of an iron and steel material by nitriding treatment is prevented from being oxidized by induction quenching, so that unevenness in film thickness between different portions of an oxidization-inhibiting film does not easily occur, with the result that a nitrogen-containing compound layer obtained after high-frequency heating remain uniformly.
