The Metal Finishing Association of California has completed the 10th year of the Bright Design Program with the Pasadena College of Design, this year conducting the final presentations online to allow for social distancing during the coronavirus crisis.
Over many years, AESF/NASF stalwart Jack Dini contributed a series of fascinating columns to Plating & Surface Finishing, under the title Fact or Fiction?. What follows is a welcome addition to his output for the NASF. Still the prolific writer, Jack discusses celebrities (both scientists and non-scientists) who once worked in electroplating.
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.
