This 1964 paper describes the first time that anyone had been able to photograph work of this type on chromium - the direct microscopic observation of the deposition of chromium on nickel and other basis metal surfaces. This classic study provided information on the effect of the surface condition of the substrate and plating variables on the initial stages of deposition, covering the growth to form a coherent deposit, and the later development of the cyclic pattern of cracking with its associated hydrogen gas evolution.

NASF/AESF Foundation Research Project #121: Development of a Sustainability Metrics System and a Technical Solution Method for Sustainable Metal Finishing: 3rd Quarterly Report
This report covers the third quarter of project work (October-December 2020) on this project at Wayne State University in Detroit. The objective is to help metal finishing plants to conduct a self-managed sustainability assessment and identify technical solutions for sustainability performance improvement. The reader is invited to contact Dr. Huang in identifying plating shops willing to participate in this program.
The NASF has released its monthly Public Policy Update identifying a few of the emerging issues at the federal level as well as the association’s actions across key states.
Electro-codeposition of MCrAlY Coatings for Advanced Gas Turbine Applications - 12th Quarterly Research Report
The aim of this research is to seek a sulfur-free plating solution for electro-codeposition of (Ni,Co)-CrAlY composite coatings. In this quarter, the coating plated in the sulfur-free, all-chloride plating solution with sodium lauryl sulfate wetting agent showed the best oxidation performance. This coating also demonstrated much better oxidation resistance that the bare CMSX-4 alloy.
The registration deadline for NASF’s Plating Essentials course is February 23. The course offers an overview of critical finishing subjects.

NASF is moving its annual SUR/FIN event and Manufacturing & Technology Conference to November 2-4, 2021 in Detroit, Michigan.
A recent development based on porous anodized aluminum (PAA) and metal nanowire deposits is presented here, which may become a competitive alternative to paint and organic coatings. By controlling the conditions for anodizing and metal electrodeposition, coatings in a wide spectrum of colors can be produced, including greys, black, blues, purples and greens.
Over many years, well-regarded AESF/NASF contributor Jack Dini contributed a series of fascinating columns to Plating & Surface Finishing, under the title Fact or Fiction?. The year 2020 saw a return of Jack’s writings from time to time, and here, he offers more material for 2021.

Nanostructure of the Anodic and Nanomaterials Sol-Gel Based Materials Application: Advances in Surface Engineering
Porous alumina can be fabricated electrochemically through anodic oxidation of aluminum. This paper reviews sol-gel chemistry and applications, which also offers unusual nanoporous microstructures. The ability to control pore chemistry at different scales and geometries, provides excellent bioactivity, enabling the entrapment of biologically active molecules and their controllable release for therapeutic and medical applications.
This republished 1944 AES convention paper presents an historic perspective of the early days of plastics in surface finishing - using them and plating on them, in the waning years of World War II. The discussion reviews the uses of plastics in plating equipment and processing at that time, as well as the coating of the plastics themselves, with accompanying application photos. You will note that today’s conventional plating-on-plastics processes lay far in the future. Surprisingly, CVD processes are discussed.
