New developments in coating and surface treatment technology has seen nanoindentation gain wider acceptance. Combination of ISO and ASTM standards for nanoindentation and availability of off-the-shelf options from different vendors has also contributed to adoption of this technique in many industries. Given the limitations of traditional hardness testing techniques, nanoindentation testers are viewed as tools that can give a better understanding of the interactions between surfaces or against abrasive elements. The wealth of information about the mechanical properties derived from a nanoindentation test defines the true strength of a material.

Historically, metal finishing racks have come a long way in their design. The crudest form of racking is simply a wire twisted onto the part. With the production and quality requirements of today, an expensive piece of copper wire will not suffice. The parts must be presented to the anodes with consistency to ensure visual and measurable quality requirements. For decorative automotive finishes of today, parts require custom racking. In this paper, I will review some basic concepts for rack design and maintenance.

In the past, engineers of quality assurance department matched color by eyesight or colorimeter to identify the change of hue. However, the method does not offer the best accuracy, nor does it indicate color strength. In this study, Everlight Chemical Industrial Corporation attempted to find a better measurement of the color strength and used the statistical analysis to get the estimated equation.

For more than 80 years now the most generally accepted process for the preparation of aluminum and it alloys for plating has involved the use of a “zincate” or “stannate” processing solution. Environmental issues relative to the use of these processes are becoming more and more of a problem. The process itself is long and involved and will differ from one alloy to another. This article presents a much more environmentally acceptable alternative that is considerably easier to work with, gives far more consistent results and is more cost effective.

Magnesium and its alloys are increasingly being used in a wide range of applications, from aircraft to motor vehicles to consumer electronics because of the low density, high specific strength and stiffness [1-5]. However, since magnesium exhibits high chemical and electrochemical activity, its alloys suffer from poor corrosion resistance, often leading to structural or mechanical failure. Magnesium corrodes rapidly when exposed to salt water, moisture or acidic liquids or gases. Many methods have been used to protect magnesium alloys by inhibiting corrosion or slowing down the reaction mechanisms, including use of conversion coatings, anodizing, electroplating and addition of corrosion inhibitors.
