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.

Anodizing

Sulfuric / Organic Electrolytes and Total Quality Improvement (TQI) for Present / Future Anodizing Requirements

After the last 12 years of developmental improvements and successful operation in production and selective brush anodizing, we present formulations for the new revised three-part organic acid blend. This ionic active blend detailed here can benefit all sulfuric anodize electrolytes to meet today's more demanding quality, specifications and production requirements.

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.

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.

Iron Tungsten Alloy Plating with Low Friction and Wear Resistance

The modern automotive industry has been striving to reduce energy loss caused by friction. An alloy plating film developed by finely crystallizing iron and tungsten demonstrates both a high level of hardness and excellent ductility. In addition, low friction can be achieved by its application under a layer of lubricant. It also has the merit of greater cost performance as compared with DLC produced with PVD technology.

Calculating Applied Media Force during Vibratory Finishing

What appear to be identically set-up vibratory bowls will finish identical loads of parts in varying time cycles. This paper offers a new technique to better predict what the operator will produce, by measuring the force applied to the parts. It is the efficiency of that force which controls the efficiency and speed of the refinement cycle.
