The Study of Copper Anodes in Acid and Cyanide Plating Baths

The 1956 Carl E. Huessner Gold Medal Award was given to Charles Faust and William H Safranek for Best Paper appearing in Plating or the AES Technical Proceedings in 1955, and their paper is republished here in a series on the AES/AESF/NASF Best Paper Awards. Their work involves an evaluation of anodes for copper plating at the time when OFHC anodes were first emerging in use.

Electroless Nickel-plated Steel versus Stainless Steel: Case Studies

This paper highlights two case studies of manufacturers that have replaced, or done studies to replace, stainless steel with electroless nickel-plated mild steel. In both cases, cost savings could be realized while maintaining or improving product quality.

Methods and Formulas to Determine Internal Deposit Stress in Applied Metallic Coatings

Internal stress exists in electroplated and chemically applied metallic coatings. This paper reviews the test procedures for measuring deposit stress and the formulas used to calculate stress values. Many formulas used require modification to obtain actual internal stress values. Errors in this regard are examined and common mistakes are explained.

Electroplating

Chromium-free Etching and Palladium-free Plating of Plastics

Plastics are replacing metals in the manufacture of many parts, and quite often there is a need for metallic coatings on the plastics and other non-conductors. This paper will describe new processes of preparing ABS plastic substrates for subsequent metallization.

Anodizing

Toxic Heavy Metal Free Stabilized Electroless Nickel Processes

This paper will introduce an advanced alternative to Pb and Cd-free electroless nickel processes, which is completely free of toxic heavy metal (THM) stabilizers. The process and deposit characteristics will be discussed and compared to the traditionally Pb stabilized electroless nickel.
