How do we compete with foreign governments for our automotive parts?

This is Part 4 of a four-part article consisting of the full report of AES Research Project #3, Adhesion of Electrodeposits, done at the University of Michigan in the mid-1940s, following the end of World War II. It contains a commentary by industry people on the published methods for measuring adhesion.

Originally published in 1980, this paper was the second on AES Research Project #41, plating on aluminum, at the National Institute for Science and Technology.  A study of the morphologies of zinc and tin immersion deposits on Al and its alloys showed that zinc formed epitaxial deposits on alloys, as noted on pure Al.  Similarities exist between the zincate and stannate processes; in particular, the same crystallography orientations are active in both systems.  Comparisons between zinc deposits produced from solutions containing ferric chloride and Rochelle salts and deposits from the same solution without these additions show that ferric chloride plays a fundamental role in the deposition process. 

Quesion: What are some of the alternative methods for determining the cleanliness of a surface?

This NASF-AESF Foundation research project report covers the third quarter of project work (July-September 2018) on this AESF Foundation Research project at the Tennessee Technological University. The objective of the work is to study and optimize the MCrAlY electro-codeposition process to improve the coating oxidation/corrosion performance.  In this quarter, studies continued on the effect of current density on CrAlY particle incorporation in electro-codeposited Ni-CrAlY composite coatings, focusing on the current density range of 20 to 60 mA/cm².

The NASF Research Board has funded a research grant at the Tennessee Technological University, under the direction of Professor Ying Zhang.  The objective is to study and optimize the MCrAlY electro-codeposition process to improve the coating oxidation/corrosion performance.  In this reporting period, the study studied a sulfur-free fluoborate plating solution.  Although the fluoborate solution is sulfur-free and offers high plating rates, the CrAlY powder was attacked by the fluoborate anion.  The fluoborate-based plating bath may be suitable for codeposition of more inert particles but not for active CrAlY-based powders. 

I have a good background on the chemistry of solvent-containing and waterborne materials, but I will have to do some additional work on better chemical strippers for powder coatings because we find them more difficult to strip. My guess is that in addition to being thicker, possibly denser and less porous, there are some chemical differences as well. Can you steer me toward some sources of this type of information?

My question is this: Do we still need to run this incinerator since we aren’t producing anything that would harm the environment, or can we at least turn the temperature down? We currently run it at 1200°F. I have asked, but nobody seems to know.

June saw annual meetings and conferences for two of the largest trade groups in surface finishing, as the National Association of Surface Finishers and the Chemical Coaters Association International held gatherings in Grand Rapids and Sarasota, respectfully. The Powder Coating Institute held its annual meeting in late May in Austin Texas.

In your reply to DW in the January issues (“Spent Bulbs as Hazwaste”), you stated that New York and California mandates that all spent fluorescent bulbs are to be recycled no matter their mercury content. That statement is partially true. In New York there is an exemption for small businesses.
