摘要： There is provided a nitrided layer repair method in which a molten metal is pressurized and solidified, and thus a nitrided layer formed on a cavity surface of a mold used to form a casting object is repaired. In the nitrided layer repair method, a nitriding source is applied to the cavity surface, and the cavity surface of the mold is nitrided by heating and pressurizing the cavity surface using the molten metal.

摘要： [Task] There is provided a mold release agent for forming a water glass-containing sand mold with high release properties which can prevent attachment of a water glass to a flask and the accumulation of the water glass on the flask in the formation of the sand mold when using the water glass as a binder.[Solution] The mold release agent for forming the water glass-containing sand mold is structured to contain an organic compound, the organic compound having a proton-donating functional group that reacts with the water glass to produce silicon dioxide. The water glass contained in a raw material for the sand mold reacts with the proton-donating functional group contained in the mold release agent so as to produce silicon dioxide. Since silicon dioxide has no adhesion, it can prevent that the attachment (fixing) of the water glass contained in a formed sand mold to the flask and the accumulation of the water glass on the flask.

摘要翻译： [任务]提供了一种用于形成具有高释放性能的含水玻璃的砂模的脱模剂，其可以防止水玻璃附着到烧瓶上，并且水玻璃在烧瓶中的积聚形成砂使用水玻璃作为粘合剂时的模具。 [解决方案]用于形成含水玻璃的砂模的脱模剂被构造成含有有机化合物，具有与水玻璃反应产生二氧化硅的质子供体官能团的有机化合物。用于砂模的原料中所含的水玻璃与脱模剂中所含的质子供体官能团反应，生成二氧化硅。由于二氧化硅没有附着力，因此可以防止将形成的砂模中包含的水玻璃附着（固定）到烧瓶上，并且水玻璃在烧瓶上的积聚。
