Zusammenfassung:To provide a vanadium membrane having a low frictional coefficient in order to prevent abrasion of a mold surface or a damage to a material to be molded caused by contact friction at the processing time of the material to be molded.SOLUTION: In a silica vanadium carbide membrane containing vanadium, silicon and carbon, the total of a vanadium element concentration, a silicon element concentration and a carbon element concentration in the membrane is 90 at% or more, or otherwise, the vanadium element concentration is 8-30 at%, the silicon element concentration is 8-30 at%, and the carbon element concentration is 40-80 at% in the membrane.SELECTED DRAWING: Figure 1 【課題】被成型材の加工時における接触摩擦に起因した金型表面の摩耗や被成型材の傷つきを防ぐための、摩擦係数が低いバナジウム膜を提供する。【解決手段】バナジウムと、珪素と、炭素とを含有する珪炭化バナジウム膜において、膜中のバナジウム元素濃度と、珪素元素濃度と、炭素元素濃度の合計を90at%以上とする。あるいは、前記膜中のバナジウム元素濃度が8〜30at%、珪素元素濃度が8〜30at%および炭素元素濃度が40〜80at%とする。【選択図】図1
