Abstract

A material for a sheet type sealing element relates to a material for a sheet type sealing element used for a steam turbine, a combustion engine and an aeroengine. The invention mainly aims to solve the problems that the existing sheet type sealing element material has low surface hardness and is not wear-resistant and easy to wipe off the air wedge. It is composed of C, Si, Mn, Cr, Ni, Cu, V, Co and Fe; the weight percentage of each component is as follows: 0.068% of C, 1.08% of Si, 1.49% of Mn, 1.86% of Cr, 6.57% of Ni, 0.206% of Cu, 0.198% of V, 0.25% of Co and the balance of Fe. The advantages are high surface hardness, increased wear resistance and integrity of the air wedge after long-term use, and reduced influence of high temperature on the surface hardness of the air wedge.

Description

Material for sheet type sealing member
The technical field is as follows:
the invention relates to a material for a sheet type sealing element for a steam turbine, a combustion engine and an aeroengine.
Background art:
the existing thin-sheet sealing element has low surface hardness, is not wear-resistant and is easy to wipe off, and the higher the temperature is, the faster the abrasion is.
The invention content is as follows:
the technical problem to be solved by the invention is to provide a material for a sheet type sealing element, which has high surface hardness, increases the wear resistance and the integrity of an air wedge used for a long time, and reduces the influence of high temperature on the surface hardness of the air wedge.
The above object is achieved by:
it is composed of C, Si, Mn, Cr, Ni, Cu, V, Co and Fe; the weight percentage of each component is as follows: 0.068% of C, 1.08% of Si, 1.49% of Mn, 1.86% of Cr, 6.57% of Ni, 0.206% of Cu, 0.198% of V, 0.25% of Co and the balance of Fe. The material is smelted by a high-temperature (over 1800 ℃) vacuum converter.
The invention has the advantages that: the surface hardness is high, the wear resistance and the integrity of the air wedge after long-term use are improved, and the influence of high temperature on the surface hardness of the air wedge is reduced.
The specific implementation mode is as follows:
it is composed of C, Si, Mn, Cr, Ni, Cu, V, Co and Fe; the weight percentage of each component is as follows: 0.068% of C, 1.08% of Si, 1.49% of Mn, 1.86% of Cr, 6.57% of Ni, 0.206% of Cu, 0.198% of V, 0.25% of Co and the balance of Fe. The material is smelted by a high-temperature (over 1800 ℃) vacuum converter.
The performance parameters of the material are as follows: density: about 5.5; tensile strength: 45.5 Kg; the compressive strength is 83.4 Kg; coefficient of expansion (1.02). times.10(-5)。
