Premature cleavage of ship plating under reversed bending
… of 39 bending specimens cut from actual ship plating were tested and on that basis a 3-D failure surface was constructed for the AH36 steel, suitable for practical applications. The failure surface was formed in terms of compressive pre-strain, temperature, and reverse tensile strain. …

Treatment of plating plant wash waters by ion exchange
… exchange of the wash waters from a mixed electroplating operation has been investigated. The loading characteristics of a strong acid resin has been studied experimentally and by mathematical simulation. The ability to separate the loaded metals by complexation techniques during elution has been …

Metal seed deposition from organic solutions for subsequent electroless plating
… organic solutions for subsequent electroless Cu plating is being developed. The mechanism is based on spontaneous electrochemical displacement reactions. The more noble metal is reduced and deposited on the substrate surface; simultaneously the less noble metal is oxidized and dissolved into the …

Development of the gel plating process for selective gold metallization
A Gel Plating Process for selective gold metallization was developed in this thesis. The Gel Plating Process selectively plates metal on catalytic features without exposing sensitive area, of the substrate surface to a corrosive plating bath. This process utilizes an electroless plating bath and …

The effect of carbonate concentration in cyanide metal plating solutions
… in copper, cadmium, silver, and gold cyanide plating solutions on the properties of the deposits and the plating range. A 267 milliliter Hull cell was used to investigate this problem. By using this apparatus the concentration of carbonate could be readily changed, and the effect which the …

Mechanism of SPS acceleration in a PEG containing copper plating bath
… as suppressors and accelerants to copper electroplating solutions. The focus of this study is on the acceleration effect of bis-(3-sodiumsulfopropyl) disulfide (SPS) which is believed to go through an electrochemical reaction to form sodium 3-mercapto-1-propanesulfonate (MPS), the effective …

Development of a selective substrate metallization process via electorless gel plating
… form corrosion barriers for underlying metals. Plating is one metallization process which immerses the component to be coated into a chemical medium. The plating baths usually operate at temperature greater than 70°C and a pH greater than 12. Alumina is stable in this environment but AlN …

Creating Complex Hollow Metal Geometries Using Additive Manufacturing and Metal Plating
… The developed process uses electroless nickel plating on laser sintered parts that then undergo a flash burnout procedure to remove the polymer, leaving a complex, hollow, metal part. The resulting geometries cannot be produced directly with other additive manufacturing systems. Copper …

Control of electrodeposit properties of nickel and nickel alloy by pulse plating.
… on/off cycles,current density, types of plating and solution pH. The structure and composition of alloys deposited have been investigated using S.E.M and wet analyses. It has been shown that the composition of the Ni/Fe alloy deposits changed markedly with increasing current density and …

Characterisation of Potential Replacements for Nickel Compounds used in Decorative Chromium Plating
The electroplating industries use soluble nickel salts in numerous applications. Over the past few years this has become problematic due to the reclassification of these salts from a harmful substance to now a toxic substance. The introduction of the legislation REACH (Registration, Evaluation, …

The effect of chromium plating on the endurance limit of 4340 steel
… limit of AISI 4340 steel due to one chromium plating was 21 percent, based on the fatigue limit of unplated AISI 4340 steel.

An investigation into phenomena which influence the optimisation of ion plating systems
Ion plating involves the transportation of vapour through a low pressure glow discharge to form solid coatings on negatively biased substrates. Although the method has gained commercial acceptance, particularly for engineering applications, much of the underlying science of the process is poorly …
