ABSTRACT:
Ceramic head pad materials which exhibit superior toughness and lubricating material characteristics over known materials, particularly in the areas of toughness resilience, damping, solid lubricity, reduced brittleness and chipping (without a change in bulk hardness), and improved thermal expansion, result from optimizing the amount of strontium oxide (SrO) and included in a calcium titanate ceramic. In particular, a ceramic material with approximately 5% to 7% SrO in a calcium titanate matrix (with approximately 6% SrO being the optimal concentration), may be utilized to realize the aforestated improved toughness and lubricating characteristics.
