Binder Removal in Vacuum Sintering

Source: TAV: The Vacuum Furnaces Blog

Heat Treat Today previously posted Parts 1 and 2 of this series on vacuum sintering. Part 1 focused on the two processing steps of debinding and sintering. Part 2 addressed primarily the vacuum sintering furnace itself. This installment analyzes the process and variables involved with binder removal.

Andrea Alborghetti, technical manager of TAV Vacuum Furnaces and contributor to the company’s blog, provides an analysis of burning vs capturing binders, addressing advantages as well as problems that may arise and how to execute control in the process, as in this example:

“One thing that is worth clarifying is that the flames usually seen on the outlet of kilns that use combustible gases (hydrogen, for example) as the process gas, were not originally designed to burn the binder disassociation residues to reduce emissions to the legal limits. Rather, it is solely for disposing of the emitted hydrogen safely, thus avoiding hazardous, potentially explosive atmospheric concentrations being created outside of the kiln.”

Seven Types of Annealing, and Why Bearing Manufacturers Should Turn to Spheroidization

June 5, 2018 / ANNEALING TECHNICAL CONTENT, FEATURED NEWS, MANUFACTURING HEAT TREAT

Sources: Machine Manufacturing; Knergize.com

Heat treating more often than not includes the process of annealing in order to induce precise softness; to alter ductility, strength, or properties; or to produce a definite microstructure. Because of the wide variety of steels and metal alloys, it is important for heat treaters to match the correct annealing process with the steel grade and to the application of the parts being treated.

Machine Manufacturing has provided a summary of the annealing process and listed seven types of annealing, describing the process and the objectives for each. Included in the list are:

Complete Annealing
Isothermal Annealing
Incomplete Annealing
Spherification Annealing
Diffusion, or Uniform, Annealing
Stress Relief Annealing
Recrystalization Annealing

And to take the analysis into more specific types of annealing, over at Knergize.com, Dr. S.B. Sarkar discusses Spheroidized Annealing and its benefit to bearing manufacturers, describing the metallurgical science behind the process, noting the need to adhere to international standards and specifications, and addressing equipment management and quality control of the process.

Gyro Stabilizer Finished with Heat Treating at Texas Forge

May 30, 2018 / FEATURED NEWS, FORGING NEWS, MANUFACTURING HEAT TREAT, MANUFACTURING HEAT TREAT NEWS

A closed die forging company, headquartered in Ellwood City, Pennsylvania, recently launched a new marine product line for a gyro stabilizer designed to improve the boating experience by eliminating boat roll, the rocking motion that causes seasickness, fatigue, and anxiety.

The Ellwood Closed Die Group introduced the line for the gyro stabilizer developed by Maryland-based Seakeeper, which also includes several finish-machined flywheels that are assembled into the gyro stabilizers. From start to finish, Ellwood Texas Forge Navasota (ETFN), located in southeast Texas near its sister company, Ellwood Texas Forge (Houston), utilizes the entire Ellwood Group supply chain to manufacture the flywheels. Raw material melted at Ellwood Quality Steel (EQS) and procured from Ellwood City Forge (ECF) is heated and forged on various pieces of equipment within the ETFN facility to produce the near net shaped forgings. After heat treatment and processing, the forging is then rough machined, non-destructively tested for part quality and finish machined to extremely tight tolerances.

Both Texas-based forge facilities provide in-house heat treatment, along with die sinking, cutting, testing and machining capabilities to serve the aerospace, construction, defense, general industrial, marine, mining, oil & gas, and power generation markets.

Seakeeper is based in California, Maryland, with locations in Europe and Asia.

Photo caption: “How It Works: Inside a vacuum encapsulation, a flywheel spins at speeds of up to 9,700 rpm. When the boat rolls, the gyro tilts fore and aft (processes), producing a powerful gyroscopic torque to port and starboard that counteracts the boat roll.”

Engineers considering the advantages and disadvantages of surface treatments typically have a usable lifespan, surface hardness, and fatigue strength in mind. As a process, both gas and ion (plasma) nitriding avoid the issues involved with coatings and achieve similar metallurgical properties, and the compound zone increases corrosion resistance. But what are other areas in which the two processes can be compared, and what are their differences? It’s good to know, particularly since the latter could significantly make a direct impact on the end product.

Jacob McCann, a process metallurgist with AHT Corp., provides a specific list of pros and cons of gas nitriding and ion (plasma) nitriding in our Technical Tuesday feature for today.

World’s First Carbon-free Aluminum Smelting Process Developed in Joint Venture

May 17, 2018 / ALUMINUM PROCESSING NEWS, MANUFACTURING HEAT TREAT, MANUFACTURING HEAT TREAT NEWS

An Australian-British metals and mining corporation based in London in conjunction with a Pittsburgh-based aluminum producer recently announced an innovative process to make aluminum that produces oxygen and eliminates all direct greenhouse gas emissions from the traditional smelting process.

The new venture between Rio Tinto and Alcoa Corporation, known as Elysis, to develop the process and license the technology so that it can be used to retrofit existing smelters or build new facilities. Elysis will be headquartered in Montreal with a research facility in Quebec’s Saguenay–Lac-Saint-Jean region.

When fully developed and implemented, it will eliminate direct greenhouse gas emissions from the smelting process and strengthen the closely integrated Canada-United States aluminum and manufacturing industry. The patent-protected technology, developed by Alcoa, is currently producing metal at the Alcoa Technical Center, near Pittsburgh, Pennsylvania, where the process has been operating at different scales since 2009.

“This is a revolutionary smelting process that can deliver a significant reduction in carbon emissions. It builds on the key role aluminum has to play in driving human progress, by making products infinitely recyclable, stronger, lighter and more fuel efficient,” said Rio Tinto chief executive J-S Jacques.

Vincent Christ, who brings more than 30 years’ experience at Rio Tinto Aluminium, has been named Chief Executive Officer of Elysis.

A Heat Treater’s Primer on Getter Materials

May 15, 2018 / FEATURED NEWS, MANUFACTURING HEAT TREAT, MEDICAL HEAT TREAT NEWS, VACUUM FURNACES TECHNICAL CONTENT

Source: VAC AERO International

A common dilemma for operators of vacuum systems is to protect the integrity and maintain the life expectancy of components when the presence of unwanted gaseous contaminates threatens to destroy the sensitive materials in the processing environment. Getter materials are the MVPs that step up to the plate to protect work in a low-pressure vacuum environment.

Table 1 [1] Getter Capacity of Common Materials

The folks at VAC AERO International have provided a primer on getter materials which answers the heat treater’s questions, such as:

What is a getter?
What are the properties of getter materials?
What materials are best as getters for most heat-treating applications? What about for more sophisticated applications?
What are non-evaporative getters, and what role do they play?

“For heat treaters, getters are often considered a last resort to help keep parts ‘bright and clean’. In point of fact, they play an important role in successful vacuum processing of many highly sophisticated products and materials. As a result, we need to do a better job of understanding their role; how and where they can help.”
