MetalTech: Effects of automated substrate cooling on HVOF-deposited WC-CoCr coatings

MetalTech article
For thermal spray coating applications that require precise control of substrate temperature during deposition to achieve optimum performance of the final part, Air Products’ thermal spray cooling technology can help. By optimizing temperature control and minimizing coating oxidation during the spraying process, our technology can help you:
improve productivity of many conventional operations
eliminate the need for interpass cooling breaks, thus enabling powder and process gas savings
preserve substrate properties
decrease residual stress gradients at coating interfaces
enable applications of soft masking materials
increase the deposition efficiency of WC-CoCr coatings
minimize decarburization of the WC phase

Read our technical presentation to learn more about engineering solutions for improved quality, deposition and production throughput.

What’s your furnace control strategy?

furnace control strategy
The key to realizing optimum fuel savings, cycle time reduction, uniform heating and lower emissions with oxy-fuel burners requires a successful furnace control strategy. At AISTech 2013, technical experts from ArcelorMittal and Air Products will present the results of an oxy-fuel combustion trial conducted in a soaking pit furnace for the reheating of steel blooms. Attend their presentation in Pittsburgh to learn how an improved furnace strategy can yield significant results when switching from air-fuel to oxy-fuel combustion.

Factors affecting nitrogen efficiency in aluminum extrusion processes

aluminum extrusion
For many years, nitrogen has been widely used by aluminum extruders to improve production rates, surface finish and die life. When implemented correctly, nitrogen die shrouding can save more than $300,000 per year—but most operations have one or more process issues which can be easily identified and overcome to realize the full benefits of nitrogen shrouding and die cooling.

Ask the expert

Russell Hewertson
Russell Hewertson
Manager of Combustion Technology


Q: Why do people use oxygen for combustion when air is free?

A: The simplified answer is because 80% of air (the nitrogen) doesn’t help your process and, in fact, can hurt it. Since nitrogen doesn’t burn, it can negatively impact your operation—whereas, combustible oxygen provides a host of benefits. You can read Russ’s full answer or listen to a video where he explains more details on our website.
