Research for Q235 steel argon arc cladding FeCoCrMoCBY alloy coating

Abstract

The invention relates to a research for a Q235 steel argon arc cladding FeCoCrMoCBY alloy coating. The Fe(48-x)CoxCr15Mo14C15B6Y2 (x=0,7,9) alloy coating is obtained in the manners that a tungsten argon arc welding cladding technology is used and alloy powder in different proportions is prepared to be clad to the Q235 surface. The effects of process parameters such as ball milling time, coating thickness, drying and heat preservation time, welding current, welding voltage and welding speed of the alloy powder on the coating properties are researched. The microstructure, the phase, the Vickershardness and the corrosion resistance of a metallographic microscope, an X-ray diffractometer, a Vickers hardness tester and an electrochemical workstation to the iron-based alloy coating are researched.

[0002] The modernization construction in the 21st century is the fusion of informatization and industrialization, and various industrial products are also used in various complex and special environments, including one or more conditions such as high temperature, low temperature, high pressure, strong corrosion, high speed, etc. However, steel, which is the raw material of most products, may encounter wear, fracture, deformation and surface damage such as impact and abrasion in the working environment, which limits the scope of use of steel materials and reduces the The service life of the product reduces the application field, and it is easy to cause safety accidents and economic losses during the use of the product

However, Q235 steel has poor properties such as corrosion resistance and surface hardness, and is mostly used in the production of mechanical parts that do not require high performance, which is not conducive to the use of Q235 in certain ranges and limits its application fields.
