(PDF) Fe-Zn Alloy Coating on Galvannealed (GA) Steel Sheet The performance results show that Fe-10 wt.% Zn-coated GA steel sheet (coating time 7 s) has better spot weldability, lower dynamic coefficient of friction (0.06-0.07 in lubrication), and better
Abstract:According to that mini spangle is the most common defect affecting the appearance quality of hot-dip 55%Al-Zn alloy coated steel sheet, industrial experiments and statistical analysis were done to investigate the influence of cold rolling process on the formation of mini spangle. The results show that, with the decrease of rolling oil concentration, the increase of rolling time, and the increase of rolling pass, the probability of mini-spangle
55%Al-Zn Alloy Coating Scientific.NetThe microstructure of coating is similar to that of solidification bath, and which is made up of phases of rich aluminum, rich zinc, rich silicon and rare earth, and intermetallic layer of Al-Zn-Fe-Si. The rare earth phase is needle or rod, and mainly distributed inside rich zinc phase and on the interface between the coating and steel substrate.
A comparison study of sliding friction behavior between Oct 01, 2012 · A patent pending Tribo-tester was designed and built to simulate the sliding friction between sheet/strip and the nose of punch in deep drawing process.Labels 1 to 13 in Fig. 1 represent the corresponding parts constituting the tester, while the remaining numbers specify the dimension of the relevant components in mm. Output from the sensing components were input to a computer data
With the production capacity of 150,000 tons per year, colored steel coils are made from 0.15~1.20 mm of cold-rolled coils or galvanized coils as base metals, which are processed with surface phosphate or chromate coating treatment, and then topped with dual layers of fine baking paint with synthetic resins.

The thickness of the cold-rolled sheet was 1.5 mm. The aluminized PHS was produced by means of hot-dip-aluminizing in an Fe-saturated Al-10 wt. % Si bath at 680 °C. The Zn-coating was applied by means of hot-dip-galvanizing in an Fe-saturated Zn-0.22 wt. % Al bath at 460 °C. The thicknesses of the Al-Si coating and Zn coating were
Fe-Zn Alloy Coating on Galvannealed (GA) Steel Sheet to Jun 06, 2014 · Galvannealed steel sheets (GA) have become the mainstream steel sheet for automobile applications because of their superior corrosion resistance, paintability, and weldability. To impart specific properties, different coatings on GA steel sheet were reported to improve properties further. In this context, we have developed an electroplating process (flash coating) for bright and adherent Fe-Zn
Hot-Dip Galvanized Sheet Steel with Excellent Press 2 Properties of Hot-Dip Galvanized Steel Sheets (GI) 2.1 Corrosion Resistance Figure 1shows the results of a corrosion test of vari-ous types of Zn coated steel sheets.2) In this test, which was conducted at seashore test site in Okinawa (approx-imately 10 m from the coastline), various types of coated steel sheets with different Zn coating
AlZn coating improves corrosion resistance. Its micro-structure consists of approx. 80% aluminum and 20% zincrich phase with a thin inter-metallic layer. Aluminum in aluzinc coating provides an additional aluminum barrier. Whereas zinc provides sacrificial protection against corrosion at cut edges.
Sheet Metal Material Selection Material Type and Its GI sheets are Zinc coated CRCA sheets. Zn coating improves the corrosion resistance. GI sheets are available in ordinary (O), drawing (D), deep drawing (DD), extra deep drawing (EDD) grades. Galvanized steel is available in various zinc plating thickness. For example 120gsm, 200gsm, 300gsm or 600gsm sheets.
