Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coating for sliding having high wear resistance and low slide resistance, as an industrial basic product having excellent practicality; and to provide a sliding component having the same, and a production method of them.SOLUTION: There is provided a coating for sliding in which a cleavage substance exists without being solid-dissolved in an alloy matrix phase containing amorphous. For example, it is preferable that the alloy matrix phase is an Fe group or an Ni group, and that the cleavage substance is WC or C. Further preferably, the cleavage substance having a grain size of 1-10 μm is contained as much as 0.1-5.0 wt.%.SELECTED DRAWING: Figure 3 【課題】実用性に富んだ工業用基礎製品として、耐摩耗性が高く摺動抵抗が低い摺動用皮膜とそれを有する摺動部品、およびそれらの製造方法を提供する。【解決手段】発明による摺動用皮膜は、非晶質を含む合金母相の中に、劈開性物質が固溶することなく存在していることを特徴とするものである。たとえば、合金母相がFe基またはNi基であって、劈開性物質がWCまたはCであるとよい。劈開性物質は、1〜10μmの粒度のものが0.1〜5.0wt％含まれているとよい。【選択図】図３
