![]() The coating created is a diffusion coating and is mainly applied on Nickel and Cobalt based superalloys. The process of vacuum brazing consists in joining metal parts with the help of a filler material without melting the base materials.įollowing a liquidus phase the filler material solidifies between the parts to be brazed, ensuring the complete adhesion of the surfaces, like a standard welding operation.Īluminizing is an aluminum-based surface enrichment for machined parts. before proceeding with repair by brazing, which otherwise would not be effective. The maintenance of these components requires a complete removal of inclusions caused by oxidation, sulfation, hot corrosion, etc. The second one, dedicated to R&D, has a thermal chamber made of graphite (77 mm in diameter by 150 mm in height) capable of reaching 2000° C temperature and 200 MPa of pressure maximum capacity of 10 Kg.įluoride Ion Cleaning, FIC, is a thermo-chemical vacuum process that works by using anhydrous gaseous hydrofluoric acid to attack oxides that form deep within cracks on the parts’ surfaces. In the Cremella plant, TAG has two systems dedicated to HIP: the first one is equipped with a cylindrical molybdenum thermal chamber (1000 mm in diameter by 1500 mm in height) able to reach the maximum working temperature of 1400° C and a maximum pressure of 175 MPa the maximum capacity of the system is 10 tons. The HIP treatment significantly improves the mechanical properties of the treated parts, increasing their resilience and workability. Hot Isostatic Pressing, HIP, is a heat treatment that involves the use of an inert gas (usually Argon) at high temperature and pressure with the aim of eliminating the microporosity/microfractures that are created inside the materials, thus enhancing their characteristics. Relentless desire to challenge ourselves, which translates into constant ![]() TAG’s customers include the biggest and most demanding big ![]() The numerous certifications achieved during the yearsĪs well as by the long commitment to our services from our customers. Of the years to reach elevated competency levels, as shown by The long experience accumulated has allowed during the course TAG formed its first aerospace division over 20 years ago.įar-sighted in its vision and courageous in facing its challenge, theĬompany thus began a new and fascinating adventure that inĪ few years will lead it to become one of the world’s reference Supported by a plan of short-, medium- and long-term investments,Īllows TAG to have the latest generation of systems, guaranteeingĪ leadership position in the field of heat treatments and to beĪble to collaborate with the major industrial groups in the world. The company strategy related to technological development, ![]() Tempering and ion nitriding the second, located in Cremella,ĭeals with special processes for the aeronautical and energy sectors. Is dedicated to vacuum heat treatments for hardening and We have two operating sites with an area of 15000 sm: the first, located in Dolzago, TAG was founded in 1988 with the objective of being at theįorefront of the heat treatment sector right from the start. Tool steels, stainless steels, superalloys, titanium and light alloys. Many different types of material can be treated such as, for example: Vacuum heat treatments, brazing, precipitation, ageing, solution, aluminizing, plasma nitriding, cryogenic treatment and other special processes. TAG is a company specialized in the heat treatments and special processes for the aerospace, aeronautical, energy and automotive markets.
