As every heat treater – captive or commercial – knows, distortion will occur. The heat treater must recognize the many reasons why distortion occurs. This applies to both ferrous and nonferrous materials.

This is the second part of David Pye's series on surface treatments.

This blog will discuss a brief comparison between low- to high-temperature-deposition methods of surface-modification treatments in relation to thermal-diffusion treatments.

This column will discuss a brief comparison between low- to high-temperature-deposition methods of surface-modification treatments in relation to thermal-diffusion treatments.

This article reviews the developments that have taken place, particularly for surface treatments, within the heat-treatment processing industry.

Bodycote completed the acquisition of Mason, Ohio-based Ellison Surface Technologies to create one of the largest providers of thermal-spray and engineered-coating surface technology services in the world. Ellison’s business is an excellent strategic fit with Bodycote’s existing Surface Technology business. The expanded Surface Technology business can offer additional technologies and added resources to consolidate its leadership in surface-coating solutions and specialist processes, including thermal-spray coating, liquid coating, thermal processing and diffusion coating.

Advanced Heat Treat Corp. (AHT) installed three new gas nitriding units at its corporate headquarters in Waterloo, Iowa. The investment doubles their gas nitriding capacity at this location and allows the company to expand its UltraGlow gas nitriding and UltraOx surface-treatment solutions. The three units vary in size, allowing for the accommodation of industries and applications including agriculture, automotive, construction, aerospace, firearms and oil and energy. One unit will be operational this month, and the additional two units will begin operation in February. AHT also plans to design and build an additional unit later this year.
