| description | The invention relates to a blade for creping a paper web from a Yankee cylinder surface, said blade comprising a steel substrate having a thickness of 0.7 mm-2 mm, the steel substrate is covered by a cermet coating that forms a working edge adapted for contact with said surface and a web impact area upon which the web impacts during creping, wherein the cermet coating comprises chromium carbides and tungsten carbides in a nickel based metal matrix and wherein the cermet coating has a porosity of < 2 volume % and a hardness of > 1100 HV0.3.
本发明涉及用于使来自杨克滚筒表面的纸幅起皱的刮刀，所述刮刀包括具有0.7mm-2mm厚度的钢基底，该钢基底被金属陶瓷涂层所覆盖，该金属陶瓷涂层形成适于与所述表面接触的工作边缘和所述幅在起皱期间撞击在其上的幅撞击区域，其中所述金属陶瓷涂层包含在基于镍的金属基体中的碳化铬和碳化钨，且其中所述金属陶瓷涂层具有＜2体积％的孔隙率和＞1100 HV0.3的硬度。 |
