Study on Cutting Performance of Gray Cast Iron Cylinder Liner

Abstract

Abstract. Cutting performance of gray cast iron cylinder has been valued in the recently years. The microstructures and mechanical properties of four sets of gray cast iron cylinder liners were compared and studied. At the same time, the effect of microstructure on the cutting performance was explored. It is concluded that uniform matrix of gray cast iron will improve the cutting performance, and the higher the graphite content, the finer the size, the better the cutting performance. Ultimately, the condition of gray cast iron with good mechanical properties and cutting performance is below: fine, curved, disordered and evenly distributed flaky graphite structure and large lamellar spacing and uniform pearlite matrix.
