Whether you are deburring, finishing, cleaning, burnishing or removing chips and plastic flash, steel media can do the job...

The First AES Scientific Achievement Award (later William Blum Memorial) Lecture presented at the AES Golden Jubilee Convention, June 15, 1959, in Detroit, Mich., for the 50th Anniversary of the Founding of the AES. (Originally published as 46th Annual Technical Proceedings - AES, 46, 39-42 (1959).)

This paper is a re-publication of the 6th William Blum Lecture, presented at the 51st AES Annual Convention in St. Louis, Missouri, on June 15, 1964.

Mechanical finishing technology, whether used for finishing or preparation, is somewhat of an orphan industry that relies almost solely on the practices of each company using the technology. Some common processes are self-explanatory; however, there are some that warrant some form of standardization…

This paper is an expanded treatment of the first part of the William Blum Lecture presented at SUR/FIN 1988 in Los Angeles by Dr. Morton Antler, 1987 AESF Scientific Achievement Award recipient. The subjects covered include friction, mechanical wear, fretting corrosion and frictional polymerization—all vital processes that affect the performance of contact finishes in electronic connectors.

Finishing companies face an array of unprecedented challenges. Decision-making is affected by these pressures. Conventional wisdom and/or the reliance on internet-based answers can lead to procurements that create unnecessary downtime, safety risks and loss. Factors compounding the pain of inadequate options and poor choices are aging plants and equipment, a shrinking manufacturing workforce and legal/policy/regulatory costs. Topics covered in this article include: (1) an overview of tanks and liners, (2) the true costs of downtime, (3) results from a recent tank and liner market survey, (4) the plastic paradox (including fires), (5) spark testing and leak monitoring technologies, (6) drop-ins, (7) what to look for from a supplier and (8) new advancements.

This article is the second of three parts of a re-publication of the 16th William Blum Lecture, presented at the 62nd AES Annual Convention in Toronto, Ontario, Canada on June 23, 1975. Dr. Ernst Raub presents a comprehensive treatise on alloy plating.

The paper is a 1975 study of just how the tin chloride / palladium chloride system worked for plated plastics, and which systems were most effective in doing the job.

This paper will discuss recent research work on the development of a functional trivalent chromium plating process from a single, simple-to-control trivalent-based electrolyte to replace hexavalent chromium plating. Hexavalent chromium plating has been used for many years to provide hard, durable coatings with excellent wear and corrosion resistance properties. However, hexavalent chromium baths have come under increasing scrutiny due to the toxic nature of the bath, effects on the environment and worker health. In this work, we are updating accomplishments to achieve properties comparable to existing hexavalent chromium plating for functional applications. Work on achieving desirable thickness, uniformity, adhesion, porosity and corrosion resistance, as well as other material properties, will be discussed.
