TTS Thermal Cycling enhances brake drum wear properties and increases strength

SEM, EDAX X-ray intensity maps, and metallographic examination of treated and untreated brake drums indicate that the TTS Thermal Cycling treatment enhanced precipitation reactions within the material and at the grain boundaries.  This will have a tendency to enhance material wear properties and increase strength by reducing residual stresses within the microstructure. The graphite flakes of the treated materials have a finer structure and are more evenly distributed. And silicon and manganese inclusions have increased in size and frequency.

Examinations indicate a microstructural transformation occurred within the brake drums resulting from the Thermal Cycling treatment.  Application of this process improves precipitation reactions and diffusion within the material and at the grain boundaries.  This has a tendency to enhance material wear properties and increase strength by reducing residual stresses within the microstructure.

The brake drums tested were determined to made of of gray graphitic cast iron, a typical material used in the fabrication of brake drums, engine blocks, flywheels and other automotive components.

Gray cast iron is very hard as result of its high carbon content, which also helps products exhibit excellent wear characteristics. However these materials are typically brittle, exhibit low impact and fracture toughness, and do not typically demonstrate yield strength unique from the ultimate tensile strength. Gray cast irons traditionally contain 2.5 - 4.0% carbon and 1 - 3% silicon, manganese, and sulfur. Their addition results in an alloy that can be cast easily, which reduces cost.

TTS Thermal Cycling improves strength and elongation of brake rotor material

Testing treated versus untreated brake rotors demonstrates that TTS Thermal Cycling increases yield strength by 14.5%, increases ultimate tensile strength by 13.1%, and lengthens the time to failure by 22.6% on average.

For the treated and untreated rotor materials, yield strength, ultimate tensile strength, Young’s modulus and the percent strain to failure were calculated and average values were determined.

Test results of the material from the two brake rotors (treated and untreated) were compared to evaluate the relative change in material strength resulting from the treatment process

TTS Thermal Cycling improves corrosion resistance of bridge tendon materials

Although both treated and untreated bridge tendon material (cable) samples experienced some corrosion as result of a salt spray test, the treated sample exhibited less surface and crevice corrosion than the untreated one. And the corrosion on the treated tendon was thinner.

Crevice corrosion is especially important, because it cannot typically be evaluated by just visual examination of the bridge tendon while in use. Destructive testing is required to see inside the twisted strands. So reducing crevice corrosion is critical to help ensure the cable doesn’t fail while in use.

Bridge tendons or wire cable is made up of multiple strands of wire twisted into a helix. Today steel is the primary material used in its manufacture.

TTS Thermal Cycling reduces loss in brake drum mass and wall thickness

In laboratory test conditions, a TTS Thermal Cycling treated brake drum exhibited 15% of the wear as compared to an untreated one. The treated drum had less loss of mass, less decrease in diameter, and less reduction in drum wall thickness.

Tests were conducted using the same gross axle weight, static loaded radius, and inertia for both treated and untreated drums.

TTS Thermal Cycling extends tool life in orthopedic operating rooms

Testing conducted by leading Canadian researchers demonstrated that treated orthopedic drill bits perform significantly better than untreated ones - in areas of function, maximum force, and torque. In fact treated drill bits wear at less than half the rate, which has the potential to reduce expenses by less frequent replacement and to decrease surgical time, frustration, and thermal necrosis.

Their conclusion was that, “Application of this technology may also be relevant to surgical cutting tools such as saw blades, burrs and reamers.”

This test was conducted on materials treated by TTS Thermal Cycling, Canada, by researchers from Division of Orthopaedic Surgery, University of Toronto, Toronto, Ontario; Orthopaedic Biomechanics Lab, Sunnybrook Research Institute, Toronto, Canada; and Sunnybrook Health Sciences Centre, Toronto, Ontario.

TTS Thermal Cycling saves money for municipal trash service

A small Florida municipality has found significant savings in operating costs for their solid waste collection service as result of having high-wear parts treated with the TTS Thermal Cycling proprietary process.

Untreated truck brakes and shoes typically lasted only 4 - 6 months on their trucks, making 700 pickups per truck each day - Monday through Friday. With treatment, they have extended their lives up to 24 months, saving money on replacement parts and the labor to install them.

Three years ago this city purchased some new trucks that use chains in the lifting mechanism. Initially they only got about 6 months wear on the chains before needing to replace them. With treatment 30 months ago, the same chains are still in use, providing them with more savings and better ROI on their investment.

 TTS Thermal Cycling saves on operating costs for concrete block manufacturer

A Florida concrete block manufacturer is able to get an average of 67% more life from its molds treated with TTS Thermal Cycling over untreated ones - going from 80-85K cycles per mold to 145K or more.

One engineer estimates their savings at about 1¢ per block, equating to almost $100K reduced operating expenses per year. In addition to purchasing fewer molds, they save on the labor costs required to replace the worn mold parts. And they experience reduced downtime, enabling their machinery to remain in valuable production mode rather than sitting idle.

TTS Thermal Cycling strengthens aluminum brake rotors

The TTS Thermal Cycling process applied to aluminum brake rotors results in a reduction of weak spots in the metal for stronger brakes that function more predictably.

Testing was conducted on 10 aluminum brake rotors - 5 treated and 5 untreated , Results showed that Thermal Cycling aligns the granular structure, resulting in tensile strengths that are virtually the same with a maximum of 400 PSI variance. The tensile strengths of untreated rotors had variances up to 9 times higher (3,600 PSI).

TTS Thermal Cycling increases tensile strength of alloys with carbides

High-speed steel cutting and drilling tools and other high-wear parts, which include carbide in their alloy, exhibit longer functional lives and higher tensile strength as result of treating by TTS Thermal Cycling. In tests we increased tensile strength by 10% as result of the alignment of the granular structure that occurs in our proprietary process.

Cobalt is present in all carbides, used as a binder in many powdered metal components and as a hardening agent for various alloys. By increasing the strength of the cobalt - we increase the strength of the carbide and therefore the tool or other part.
