Advantage compared to alumina:
zirconia exhibits better impact strength;
zirconia is harder than alumina;
zirconia can be honed to finer surface finishes than alumina. Finished to 4RMS, the zirconia liners provide a surface finish that is three to four times finer than alumina.
Based on phase transformation toughening technology and featured by good resistance to corrosion,high pressure and high temperature,high strength and rigidity,good performance and longer service life above 4000hr,the zirconia ceramic cylinder liner is applicable to the well drilling,offshore oil and natural gas development,which has deep oil reservoir and bad geological structure.
