A long history in the aviation engine industry
In the early 1950s, aircraft engine OEMs came to us when they needed to make jet engine components last longer between overhauls. Our super-hard, tungsten-carbide and chromium-carbide coatings became mainstays of gas turbine engine performance. Critical parts such as fan and compressor blades last 10 to 20 times as long with the hard wear protection of detonation-gun coatings. We led the way then, and we continue today.

In fact, in 1999, Praxair's Speedway Laboratories in Indianapolis were designated by ASM International as a historic landmark in recognition of our innovations in materials science and engineering.
