VAC AERO News, Education & Training

vacuum-furnacesVAC AERO Opens its Second Facility in Poland

First established in 2003 in Kalisz, Poland VAC AERO has now opened a second facility located in the town of Rzeszow in southeast Poland. VAC AERO’s Polish divisions offer vacuum heat  treating and brazing, vacuum carburizing, air plasma spray (APS) and HVOF protective coatings, as well as corrosion and oxidation resistant paint coatings. This will VAC AERO’s sixth vacuum heat treating, brazing and coating facility worldwide.

Vacuum Technology with "The Heat Treat Doctor"

vacuum furnacesTool Steel Carbides

Tool steel heat treatment is based on a simple premise, that to obtain the optimum performance from any given grade, every step of the heat treating process including stress relief, austenitizing, quenching, cryogenic treatment and multiple tempers must be done exactly correct. Absolute control of both process and equipment variability is one of many reasons why vacuum processing is popular in tool steel heat treatment.

Vacuum Brazing with Dan Kay

vacuum furnaceCenterline Eutectics in Ni-brazing

Joint clearances must be tight for effective Ni-brazing. Nickel-based brazing filler metals (BFM) can leave a hard, non-ductile eutectic phase in the middle of a brazed joint. The hard, non-ductile metallurgical phase-structures that form upon solidification of Ni-brazed joints must be carefully controlled, or else they can, and will, result in cracks inside the joint in stressful mechanical or thermal-cycling service inside the joint.

Metallography with George Vander Voort

vacuum-furnaceRevealing the Microstructure of Tool Steels

After we have properly prepared our tool steel specimens, it is generally best to examine them as-polished before etching unless we are simply doing a routine test, for depth of decarburization, degree of spheroidization, and so forth. Examination of selectively etched tool steel microstructures by light microscopy provides more information than standard etchants, such as nital, picral or Vilella’s reagent.

The Monty, June 29, 2006 Issue

VAC AERO Manufacturing Polska (new furnace equipment) recently exhibited at the Surftec Exhibition in Poznan, Poland. At the end of the show, the organizers present an award for the display judged to best achieve the marketing strategy of the company. The winner? VAC AERO. We could make a lot of comments but let's just say it is a rather unique approach, the VAC AERO display actually looks like a vacuum furnace. Hard to miss the marketing strategy there. Congratulations to Marketing Manager Alena Iwanowska (on the left) and her crew.
