1045 Steel

Nickel-base composite coating reinforced by in situ synthesized multiple carbide particles were fabricated on AISI 1045 steel surface by pre-placed laser cladding. Nowadays most researches focus on the wear resistance. This study mainly focuses on the corrosion resistance property. Investigate the effect of different particle distribution on corrosion resistance of the cladding layers by controlling the amount of Zr, Ti and WC. The microstructure and electrochemical property are analyzed by scanning electron microscope (SEM) and electrochemical test equipment. The maximal particle distribution density and particle area ratio appear when Zr:Ti:WC=1:2:2. The polarization curves show that in 0.05mol/L HCl electrolyte the coatings’ corrosion resistance have positive correlation with particles distribution density and particles area ratio, and all the coatings are significantly better than 314L stainless steel in corrosion resistance.

In this paper, we used two mass-produced industrial technologies, namely, thermal spraying and anodization methods, to enhance the surface characteristics of AISI 1045 medium carbon steel for use in special environments or products. The anodic film can effectively improve the surface properties of carbon steel. A sequence of treatments of the carbon steel substrate surface that consist of sandblasting, spraying the aluminum film, annealing, hot rolling, cleaning, grinding, and polishing can increase the quality of the anodized film. This paper proposes an anodization process for the surface of carbon steel to increase the corrosion resistance, hardness, color diversification, and electrical resistance. The resulting surface improves the hardness (from 170 HV to 524 HV), surface roughness (from 1.26 to 0.15 μm), coloring (from metal color to various colors), and corrosion resistance (from rusty to corrosion resistant). The electrochemical corrosion studies showed that the AISI 1045 steel surface with a hard anodized film had a lower corrosion current density of 10−5.9 A/cm2 and a higher impedance of 9000 ohm than those of naked AISI 1045 steel (10−4.2 A/cm2 and 150 ohm) in HCl gas.

Small amounts of nickel are added to titanium to improve the crevice corrosion resistance but this results in an alloy which has sheet fabrication difficulties and is subject to the formation of large Ti2Ni precipitates. These large precipitates can serve as local corrosion sites; but in a smaller more widely dispersed form, they can have a beneficial effect on crevice corrosion resistance. The purpose of the present work is to show that the addition of a small amount of Mo to the Ti-1.5Ni alloy reduces the Ti2Ni precipitate size and produces a more elongated grained microstructure. It has recently been reported that small additions of Mo to Ti-0.8 to lw/o Ni alloys produce good crevice corrosion resistance and improved fabrication properties.
