摘要：
A dry cleaning method of a Ni-based superalloy for a gas turbine, which is economical by using a conventional equipment while removing oxides formed deep in cracks stably and effectively, and a component for the gas turbine capable of effectively removing oxides formed deep in the cracks by the dry cleaning method are provided. In a dry cleaning method of a Ni-based superalloy component for a gas turbine, which removes oxides existing on the surface of fine cracks of a regenerated product using HF gas in a regeneration process of a Ni-based superalloy component that is a component material of a gas turbine operated at a high temperature, the dry cleaning method comprises the steps of: coating a mixture of PTFE(polytetrafluoroethylene) powder and volatile fluid on the surface of the fine cracks, vacuum treating the mixture coated fine cracks for a predetermined time to infiltrate the mixture into the fine cracks; treating the mixture infiltrated fine cracks at a high temperature of 800 to 1,000 deg.C.
摘要（中）：
一种用于燃气轮机的Ni基超级合金的干洗方法，其通过使用常规设备同时去除了稳定有效地形成在裂纹深的氧化物，并且能够有效地除去深层形成的氧化物， 提供了通过干洗方法的裂纹。 在用于燃气轮机的Ni基超合金部件的干式清洗方法中，该Ni基超合金部件在作为成分材料的Ni系超合金部件的再生工序中除去使用HF气体的再生产品的微细裂纹表面存在的氧化物 的干燥方法包括以下步骤：在细裂纹的表面上涂覆PTFE（聚四氟乙烯）粉末和挥发性流体的混合物，将混合物涂覆的细裂纹真空处理预定时间 将混合物渗入细裂纹; 在800〜1000℃的高温下处理混合物渗入细裂纹。
