摘要: 在Fe基金属结合剂金刚石锯片的胎体中加入弱化胎体添加剂硅铁,用万能材料试验机、摆锤冲击试验机、自动切割机等考察硅铁对胎体力学性能、锋利度、耐磨性的影响。结果表明:加入硅铁可以降低胎体的抗弯强度、韧性、耐磨性,提高胎体的锋利度和硬度,其添加质量分数以3%~5%为宜。Abstract: Silicon-iron was added into the matrix of Fe-based metal bonded diamond saw blade as a weakening agent. The effects of the agent on the mechanical properties, sharpness and wear resistance of the matrix were investigated by using universal material testing machine, pendulum impact testing machine and automatic cutting machine. The results show that the addition of silicon-iron can reduce the flexural strength, toughness and wear resistance of the matrix, and improve the sharpness and hardness of the matrix. The appropriate mass fraction of the additive is 3% to 5%.
