Vacuum Heat Treating Services from Applied Thermal Technologies, Inc

AEROSPACE HEAT TREATING

Aerospace heat treating is done for super alloy components used in the aerospace industry when they’re joined together by brazing or diffusion bonding with nickel and cobalt base filler metals. Aerospace heat treating is carried out in high vacuum furnaces by holding the parts for a long period of time to diffuse away boron and silicon. During the aerospace heat treating process our vacuum furnaces can reach temperatures to 2800 degrees F and have vacuum levels to 10-6 Torr, all metal hot zones and extremely rapid cooling. Applied Thermal Technologies Inc. personnel work closely with each customer in determining their particular requirements and are available for technical assistance for your aerospace heat treating, metallurgy and brazing questions.

BRIGHT ANNEALING

Bright annealing is the process of slowly cooling an object. Bright annealing is an integral part of making materials especially glass less brittle. The process can be used on stainless steel, cobalt, chrome, high temperature alloys and titanium. The bright annealing process is just one of the heat treating capabilities of Applied Thermal Technologies Inc. We also have the equipment to do brazing, tempering and hardening. We are a small business, with mechanics providing customer satisfaction in local and national markets. The pride of a job well done is still apparent in our interactions with our bright annealing customers and all that we do.

CERAMIC BRAZING

The lower temperature associated with ceramic brazing vs. welding can increase joining speed and reduce fuel gas consumption. Ceramic brazing can be easier for beginners to learn than welding. It can also be a cheap and effective technique for mass production. With ceramic brazing the joints generally have smooth attractive beads that do not require additional grinding or finishing. Components can be assembled with preformed plugs of filler material positioned at joints and then heated in a furnace or passed through heating stations on an assembly line. The heated filler then flows into the joints by capillary action. For thin work pieces like sheet metal or thin-walled pipe burn-through is less likely to result with ceramic brazing.

CERAMIC BRAZING CALIFORNIA

Applied Thermal Technologies, Inc. is a metal processing company that provides ceramic brazing services to the state of California. Ceramic brazing is one of the best ways to join ceramics with other ceramics or with common metals. Ceramics are often very difficult to join and welding is almost never an option. Active metal ceramic brazing can be used to join difficult materials such as carbide, diamond, sapphire, alumina, zirconia, and silicon nitride. These materials may be joined to themselves or to common metals such as stainless steel and copper with ceramic brazing processes.

HEAT TREATING CHICAGO

MEDICAL DEVICE BRAZING

Medical device brazing is a joining process whereby a non-ferrous filler metal and an alloy are heated to melting temperature (above 800 degrees F) and distributed between two or more close-fitting parts by capillary action. With medical device brazing when the braze is at its liquid temperature, the molten filler metal interacts with a thin layer of the base metal, cooling to form an exceptionally strong, sealed joint due to grain structure interaction. With medical device brazing the joints becomes a sandwich of different layers, each metallurgically linked to each other. The most common filler materials are gold in color, but fillers that more closely match the color of the base materials can be used since appearance is important to the medical device brazing end product.

MEDICAL DEVICE HEAT TREATING

Our medical device heat treating includes the process of precipitation hardening, also called age hardening. It is widely used to add strength to our medical device heat treating alloy materials. The precipitation hardening capabilities of Applied Thermal Technologies, Inc. include stainless steel, high temperature alloys and titanium. We began our company in 1992 to service the hospital and specialty components industries in Northern Indiana and have since expanded nationally. You can increase joining speed and reduce fuel gas consumption with the lower temperature associated with medical device heat treating.

MEDICAL INSTRUMENT BRAZING

Applied Thermal Technologies, Inc. is a metal processing company that provides medical instrument brazing nationwide. Brazing allows small, delicate parts to be crafted with superior strength. Brazing is accomplished by placing a filler metal with a lower melting point than the base metals between the two metals to be joined. The pieces are then heated to the melting point of the filler metal, which joins the base metals through capillary action. Vacuum brazing also allows many medical instruments to be brazed at once, increasing efficiency.
