PURPOSE:To obtain heat-insulating capacity as well as capacities of anti-abrasion and anti-seizure by providing a ceramic layer on the inner circumferential face of a cylinder main body constructed of metallic material by deposition. CONSTITUTION:For a cylinder main body 1, cast iron, steel, or aluminium is available. For a bonding material layer 2, a material that promotes the bondage between the cylinder main body and a heat-insulating ceramic layer with low thermal conductivity, such as Ni-Al alloy, Ni-Cr alloy, Ni-Cr-Al alloy, Ni-Cr- Mo alloy, or a simple metal material such as Mo can be adopted at thickness of 20-100mu. For a heat-insulating ceramic layer 3, a ZrO2 material of high thermal insulation, especially, MgO-stabilized ZrO2, CaO-stabilized ZrO2, or Y2O3-stabilized ZrO2 can be used at thickness of 100-1,500mu. For an anti-abrasion ceramic layer 4, a material with high capacity of anti-abrasion and anti-seizure such as Al2O3.TiO2 or Cr2O3 is available at thickness of 50-200mu. |
