Abstract
Friction and wear properties of TiB2/SiAlON composite ceramics slid against SiAlON ceramics were investigated in a zinc plating bath and in air. Friction coefficient of TiB2/SiAlON in a zinc plating bath was found to decrease monotonically from 0.5 to 0.1 when TiB2 content was increased from 0 to 80mass%, but it did not change in air with increasing TiB2 content and was about 0.5. No wear was observed for TiB2/SiAlON although hard particles (dross) were present in the bath, because TiB2/SiAlON were harder than the dross. Improved lubrication afforded by better wetting between TiB2/SiAlON and the molten zinc may be the primary cause for the reduction of friction coefficient.Keywords
