Special Aspects of Electrodeposition on Zinc Die Castings

Electroplating is a frequent choice to give zinc die cast components a high-quality protective and decorative surface finish, however, applying this kind of treatment for die cast zinc components presents hidden challenges. In order to overcome these issues, a thorough morphology and composition analysis of die cast items was conducted. Special aspects of zinc die cast as a plating substrate are described and linked to the die casting process.

Crack Formation during Electrodeposition and Post-deposition Aging of Thin Film Coatings - 7th & 8th Quarterly Report

This NASF-AESF Foundation research project report covers the seventh and eighth quarters of project work (July-December 2017) on this AESF Foundation Research project at the University of Houston. The objective of the work is to study fundamental and practical aspects of crack formation in electrodeposited thin films.

Reminiscences of Early Electroless Plating

The development of autocatalytic deposition was one of the most important developments in the history of surface finishing.  Here, in an article from Plating and Surface Finishing in 1984, the  AESF 75th anniversary year, Dr. Abner Brenner, considered to be the “Father of Electroless Plating,” recalls why and how it came about.

Historical Highlights of Electroless Plating

In a 1984 article in Plating and Surface Finishing, for the AESF 75th anniversary year, Charles R. Shipley Jr. recounts the history of the commercialization of electroless plating beyond the discovery of electroless nickel by Dr. Abner Brenner and Grace Riddell at the National Bureau of Standards.

Transition from a Simple Auxiliary Anode to a Fully-developed Conforming Anode System for Plating

This paper demonstrates that the use of an elaborate CAE designed conforming anode system enables plating complex exterior automotive part designs within specification.  It will be shown that the increased fixed and variable production costs that are unavoidable when operating an elaborate conforming anode system can be partially earned back by a reduction in metal consumption, and by an increased capacity due to shorter plating times.

Acid Copper Technologies for Plating on Plastics

Automotive OEM performance requirements continue to increase which presents increased challenges to the supply chain to provide acceptable parts.  This presentation will introduce a new system of acid copper technologies that have been designed to increase performance, widen the process operating window, reduce rejects and ultimately increase production capacity.

I. Rack and Anode Effects on the Distribution of Functional Chromium Electrodeposits

This is the first of three combined papers that received the AESF Gold Medal Award for Best Paper published in Plating & Surface Finishing in 1989.  Procedures for improving functional chromium thickness distribution begin with this paper that advocates useful rack designs and anode configurations.

II. The Effects of Stopoffs and Thieves on the Distribution of Functional Chromium Electrodeposits

This is the second of three combined papers that received the AESF Gold Medal Award for Best Paper published in Plating & Surface Finishing in 1989.  Stop-offs, thieves and guards are used to change the pattern of current flow and improve metal distribution. The effects may be planned or may occur unexpectedly, producing undesirable results.

III. The Effects of Shields and Baffles on the Distribution of Functional Chromium Electrodeposits

This is the third of three combined papers that received the AESF Gold Medal Award for Best Paper published in Plating & Surface Finishing in 1989.  Insulating shields and baffles redirect the flow of current and affect the thickness distribution of chromium and other electrodeposits. Many examples of these useful devices for improving the uniformity of chromium deposits are described.

Innovative Applications of Electroplating and PVD for New Material Solutions - The 54th William Blum Lecture

The following is Dr. Per Møller’s William Blum Memorial Lecture at SUR/FIN 2018, in Cleveland, Ohio on June 4, 2018, with commentary by NASF Technical Editor James H. Lindsay.  It covers a variety of projects involved with surface finishing applications, including sustainable energy.  Due to Dr. Møller’s serious illness, he was unable to make the journey to SUR/FIN.  In his stead, his longtime professional colleague, Dr. Lars Pleth Nielsen, of the Danish Technological Institute (DTI), presented the lecture.
