This year’s Heat Treatment Forum in Wroclaw included a visit to the heat treatment plant https:\/\/www.ihi-vtn.com\/en\/wilthen\/<\/a> in the program. The heat treatment plant is located just outside the border near the city of Bautzen, which is the center of the Lusatian Serbs in Saxony.<\/p>\n

\"\"<\/a><\/p>\n

Translation: “For all registered participants of the Polish Heat Treatment Forum and users of heat treatment technologies, we are also organizing a trip to the heat treatment plant of the Japanese concern IHI in Germany (near Bautzen), where everyone will be able to see a fully automated line for low-pressure vacuum carburizing (LPC). IHI is the inventor and patent holder of this technology”<\/em><\/span><\/p>\n

 <\/p>\n

Although I have known about this plant for many years, I have never been there. I only drove past it once when I was heading somewhere for climbing in Saxony. It was basically the only competitor of Bodycote Liberec<\/strong> across the border towards Zittau.<\/p>\n

The fate of the VTN<\/strong> heat treatment plant in Wilthen is somewhat tied to my history, as well as the history of Karol Forycki. He pulled off a feat when he brokered this acquisition by the Japanese company IHI Group<\/strong> in 2015. According to what can be seen on the website, it is a modern, well-maintained heat treatment operation, with NADCAP certification.<\/p>\n

But IHI<\/strong> does not only own this plant, but also owns IHI Hauzer Techno Coating B.V.<\/strong>, which was once part of Bodycote Venlo<\/strong>. I was there many times in the past, because one of my best “bosses”, Hans Veltrop<\/strong>, came from there, and Bodycote CEG Group meetings were regularly held in Venlo. However, with the acquisition of Hauzer, IHI<\/strong> also acquired a 50% stake in HVM Plasma<\/strong> in Prague, and that brings us closer to my history, because the remaining 50% is still owned by Jirka Vysko\u010dil. I have already written about him here on my blog (https:\/\/intelligent-kalam.80-240-27-133.plesk.page\/jiri-vyskocil\/<\/a>) , our history was tied to the development of the first deposition devices for TiN<\/strong>, both by arc evaporation NNO-150<\/strong> and magnetron sputtering DAM 300.<\/strong> Over time, Vl\u00e1\u010fa Proch\u00e1zka and I converted the arc evaporation device NNO-150<\/strong> to plasma nitriding, and the planar magnetron sputtering we used the latter until around 2001, when we coated by TiN<\/strong> welding glasses for Severosklo Kamenick\u00fd \u0160enov.<\/p>\n

\"\"<\/a>\"\"<\/a>\"\"<\/a><\/p>\n

So much for history. That’s why I know quite a bit about both HVM Plasma<\/strong> and IHI Hauzer,<\/strong> and even though Bodycote eventually sold the entire coating branch under the IonBond brand to IHI, I never stopped being interested in this field.<\/p>\n

When I met Mr. Akihiro Horita<\/strong>, IHI’s marketing director, in Wroclaw last year, I didn’t feel like it was some kind of important secret. That’s why I was surprised that I got on the “Black List<\/strong>” for the above-mentioned excursion to VTN<\/strong>. They simply excluded me from the list of participants.<\/p>\n

In the end, nothing happened, just a strange feeling as to why I was on the “Black List<\/strong>“. But there’s no point in dealing with that anymore, so I can only assume that it’s thanks to the representation of ECM Technologies<\/strong> and their LPC,<\/strong> which competes with IHI’s LPC<\/strong>. I have no idea what I could be looking at. I understand the difference between IHI’s LPC<\/strong> and ECM’s LPC<\/strong>, but these are processes that are unrecognizable from the outside of the device.<\/p>\n

I’m just glad that even in Japan they already know who I am…<\/p>\n
