Micro-Brazing of Stainless Steel Using Ni-P Alloy Plating

Vacuum Brazing of Zirconium-Based Alloy and 321 Stainless Steel Using Titanium Based Filler Metal

Both Zirconium-based alloys and 321stainless steel are widely used as engineering alloys due to their good mechanical properties. Conventional fusion welding techniques for Zr alloys and stainless steel are not feasible due to the formation of brittle intermetallic compounds such as (Zr3Fe, ZrFe2 and Zr2Fe) and corrosion cracking. Brazing is one of the most wide...

Nickel-chromium-based Amorphous Brazing Foils for Continuous Furnace Brazing of Stainless Steel

Effects of Pretreatment Prior to Electroless Ni-P Plating on Fatigue Behavior of SAE 1045 Steel

Electroless Ni-P (EN) plating, as an important group of metallic coatings, employed in a wide range of industrial applications. The current work aims to investigate the effects of pretreatment process before EN plating on fatigue behavior of SAE 1045 steel. The specimens of rotating bending fatigue test were prepared from the steel in two series. A group of samples used in as-polished con...

Electroless Deposition of Ni-Cu-P Alloy on 304 Stainless Steel by Using Thiourea and Gelatin as Additives and Investigation of Some Properties of Deposits

In this research a layer of Ni-Cu-P was deposited on 304 stainless steels by using gelatin and thiourea as additives in a sulfate solution. In order to determine the properties of deposited layers, a microhardness tester was used for microhardness measurement, X.R.D. for microstructural analysis, and a scanning electron microscope equipped with E.D.X. for determining morphology and analyzing th...

Corrosion Protection of Steel Using Nonanomalous Ni-Zn-P Coatings

A novel technique for obtaining nonanomalous Ni-Zn-P coatings with high Ni content ~74 wt % as compared to 15-20 wt % in the conventional plating method! has been developed. These coatings show promise as a replacement for Cd in sacrificially protecting steel. Ni-Zn-P coatings were deposited using an electroless method from a solution containing NiSO4 , complexing agent and ammonium chloride. V...
