Abstract
Diamond grinding wheel was prepared by hot-press process to investigate the influence of Ti, Ni, and Co on the property of Al-based bonding agent and the binding effect of bonding agent with diamond frit. Fracture morphology of the wheel, bonding effect between the agent and diamond frit, and distribution of main elements in the bonding agent were studied by SEM. Results showed that Al-Sn-Ti-Ni-Co was an acceptable bonding agent system. Fracture surface of the wheel was smooth when it was sintered at 300 °C. Some of the Al-based bonding agent retained on the diamond surface. Ti and Ni segregated or formed independent phase in the agent. This would reduce the plasticity of the bonding agent and improve its grinding capability. Co distributed uniformly in the bonding agent and thus increased the retention of bonding agent to diamond. By adding Ti, Ni, and Co, the property of Al-Sn-Ti-Ni-Co bonding agent is improved.
