    • A mold for continuous casting comprises a copper or copper alloy mold substrate and a sprayed coating film formed on non-blasted inner surfaces of the substrate with or without a metal plated skin layer provided between the substrate and the film. For the formation of the sprayed coating film, particles of at least one tungsten carbide-based wear-resistant material having a particle size of from 5 .mu.m to 53 .mu.m and having a hardness capable of anchoring in the inner surfaces of the substrate are subjected to high pressure/high velocity oxygen fuel coating under conditions where the particles remain at least partially non-fused on application of heat from a spraying flame. By this, a layer directly anchored in the inner surfaces of the substrate or in the skin layer, if present, is formed at least as one layer of the sprayed coating film formed in a total film thickness of from 0.01 to 6 mm. No thermal fusing treatment is necessary since the bonding between the substrate or skin layer and the layer is strong.
    • 用于连续铸造的模具包括铜或铜合金模具基材和形成在基板的未喷砂的内表面上的喷涂涂膜,其具有或不具有设置在基板和膜之间的金属电镀表皮层。 为了形成喷涂膜,可以使用粒径为5μm〜53μm的具有能够固定在基板的内表面的硬度的至少一种碳化钨系耐磨材料的粒子, 在施加来自喷射火焰的热量的颗粒保持至少部分不熔化的条件下经受高压/高速氧燃料涂层。 由此,直接锚固在基板的内表面或表皮层(如果存在)中的层形成为至少一层喷涂的涂膜,其总厚度为0.01至6mm。 不需要热熔融处理,因为衬底或表层与层之间的结合是强的。
