指出，磨料磨损情况下喷涂层材料的硬度应是磨料的１．５－１．６倍。含Ｂ４Ｃ热喷涂层的耐磨粒磨损强度可达２３～２７ＧＰａ，是建筑工地泥浆泵柱塞的良好喷涂材料。由于Ｂ４Ｃ在喷涂过程中容易分解；必须在其表面包覆金属。含金属包覆Ｂ４Ｃ热喷涂层的耐磨粒磨损寿命可达２
It is pointed out that the hardness of the material of the sprayed coating under abrasive wear should be 1.5-1.6 times that of the abrasive. B4C thermal spray coating with abrasive wear resistance of up to 23 ~ 27GPa, is a good site construction mud pump plunger material spray. As B4C in the spraying process easy to decompose; must be coated with metal on its surface. Wear-resistant metal wear B4C thermal spray coating life of up to 2
