説明
Ni-Al intermetallic compounds containing silicon were coated onto a spheroidal graphite cast iron substrate through combustion synthesis. In this paper, effects of silicon addition on coating characteristics, such as constituents, hardness, wear resistance and adhesive strength, were investigated. A differential thermal analysis exhibited that silicon addition to Ni-Al green powder compacts lowered both a combustion and an ignition temperature with an increasing exothermic value. All of the coating layers consisted of multi-constituents with layers along the bonding interface. Al-Si liquid phase generated in the silicon added coating decreased void fraction in coating layers. Synthesized nickel aluminide coating layers had hardness of over 600 HV in the silicon addition up to 9 atomic percent. All of the coating layers showed drastically improved wear resistance compared with that of an FCD substrate. Adhesive strength of coatings was improved by silicon addition to Ni-Al green powder compacts due to thinning of the brittle layer along the bonding interface.
