Embodiment 1

[0046] (1) Experimental materials

[0047] 1. Base material

[0048] The base material is rolled Q235 steel. Due to the storage time and storage environment, there are rust, stains and grease on the steel surface. These factors will have an adverse effect on the subsequent surface cladding process. Pretreatment of the substrate surface. First use an angle grinder to remove the rust stains on the surface of Q235 steel and polish the surface brightly, then use absorbent cotton dipped in absolute ethanol to wipe and clean the surface, then use a hair dryer to dry the ethanol and place it in a drying box spare.

[0049] 2. Preparation of cladding coating

[0050] (1) Alloy coating material selection

[0051] Seven alloys of Fe, Co, Cr, Mo, C, B, and Y are selected as the prepared materials, and the molar ratio of each element is 48-x:x:15:14:15:6:2, that is, Fe 48-x co x Cr 15 Mo 14 C 15 B 6 Y 2 (x=0,7,9). Wherein the total mass of the powders of different components i...

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.

Description

technical field [0001] The invention relates to the field of amorphous alloy coating, in particular to the research on Q235 steel argon arc cladding FeCoCrMoCBY alloy coating. Background technique [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. As a widely used industrial raw material, Q235 steel is widel...
