Abstract
The aim of this study was to understand the friction, wear and solid particle erosion behaviour of metallic glass Ni78Si10B 12 in the amorphous, semi and fully crystallized states. The crystallization behaviour of Ni78Si10B 12 alloy was investigated by isothermal annealing treatments at various temperatures (210 ∼ 550°C) and times (0.2 ∼ 200 h) and a Time-Temperature-Transformation (TTT) diagram was constructed. The TTT curves indicated time and temperature dependent transitions between three structures, namely amorphous, semi-crystalline (Amorphous + alpha-Ni, Amorphous + alpha-Ni + Ni3B) and fully crystalline (alpha-Ni + Ni3B) structures. Scratch tests were performed on amorphous and fully crystallized alloys using a pyramid diamond indenter under different loads (50 ∼ 1000 gf) at room temperature. Sliding wear tests on the amorphous as well as crystallized samples were conducted against 52100 steel pin in air at room temperature. Detailed analyses of wear debris and worn surfaces were done by scanning electronic microscope (SEM) and energy dispursive spectrum (EDS) to understand the wear mechanisms. Solid particle erosion tests were carried out using two different sizes (49 and 127 mum) of SiC particles used as erodents. (Abstract shortened by UMI.)
