Abstract

Crystallization and wear behavior of the SiO₂-Al₂O₃-ZrO₂-Ba(Sr, Ca)O based glass-ceramics with addition of Cr₂O₃ are investigated. On annealing at 1273 K, SiO₂ and acicular BaSi₂O₅ crystallites are precipitated out from the silicate glass-ceramics which thereafter possess high friction coefficient and wear rate. Adding Cr₂O₃ retards the precipitation of BaSi₂O₅ and decreases wear resistance. But this retardation effect varies with the way that Cr₂O₃ is added. When Cr₂O₃ is added by ball milling, precipitation of BaSi₂O₅ is only partly retarded, and wear rate is decreased marginally. However, adding Cr₂O₃ during the smelting process, the precipitation of BaSi₂O₅ is almost fully prohibited, and BaCrO₄ and/or BaCr₂O₄ substituting BaSi₂O₅ precipitate out. The nanoscale barium chromates promote the formation at worn surfaces of a lubricating glaze layer that decreases largely the wear rate and friction coefficient.
