The Nature, Cause and Effect of Porosity in Electrodeposits: A Microscopic Examination of Nickel-Chromium Coatings after Atmospheric Corrosion
This paper is one of seven reports constituting AES Research Project #13, dealing with the nature, cause and effect of porosity in electrodeposits, performed at the then-National Bureau of Standards, in Gaithersburg, Maryland. It was one of several seminal articles produced through AES Research during the height of the automotive/decorative segment of the surface finishing industry in the 1950s and 60s.

Production Schedule Driven Automated Energy Management
Surface finishing line process automation systems are normally designed to optimize production throughput and assure compliance with operating parameters such as time-in-tank. The basic elements of automated energy management on process lines are control of energy consumption in active, standby and inactive states, primarily by ventilation, heating and cooling, agitation and filtration.
This paper presents a case study of the new process control model.

Can Electroplated Fe-C be an Environmentally Friendly Alternative to Hard Chromium and DLC Coatings?
Electroplated FeC is an efficient surface treatment based on non-aggressive chemicals with a deposition rate of ~20 μm/h at a process temperature of 50°C. The FeC coating is carbide-free and temperature stable up to ~250°C with a hardness of 750 HV, which is comparable to frequently applied hardened steels. The FeC coating has reasonable friction properties and have high affinity towards lubricants because of incorporated amorphous carbon. Hence, for certain applications, the FeC coating might be an interesting wear-protective alternative to hard chromium and to PVD-deposited low-friction diamond-like carbon coatings (DLC’s), which are rather difficult and costly to deposit on larger items.

Defects in Hard Chromium Deposits Part I: Causes and Cures
The causes of and remedies for defects in hard chromium deposits are explored in the first of this two-part P&SF article from 1984. Photomicrographs and SEM (scanning electron microscope) photographs will illustrate that most defects in various hard chromium deposits arise from defects in the basis metal. These defects may be in the original metal surface or may be caused by preplate finishing. Homogeneous hard chromium deposits can be produced only by eliminating these defects. Practical suggestions and procedures will be given.

Defects in Hard Chromium Deposits Part II: Detection, Prevention and Repair
Most defects in various hard chromium deposits arise from defects in the basis metal. These defects may be in the original metal surface or may be caused by preplate finishing. Homogeneous hard chromium deposits can be produced only by eliminating these defects. The final segment of this article describes visual and provocative methods of detecting defects. Also discussed are prevention techniques and repair operations.
