Agency: NSF | Branch: Standard Grant | Program: | Phase: SMALL BUSINESS PHASE I | Award Amount: 150.00K | Year: 2016

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is that it removes the limitations of the previous methods used to join ceramics and metals and allows for new ceramic and metal bonded parts to infiltrate novel markets. Many new ceramic and metal bonded parts will be fabricated for the automotive, aerospace, chemical, defense, excavation and nuclear industries where they are in high demand due to the favorable properties of both materials being joined. One immediate opportunity for this type of bond is the impact chisel market. Long term opportunities from this project will result in superior products being created for the cutting tool market, armor, wear plates, thermal insulation, electrical components, and many others. This new capability will change many manufacturing processes and allow engineers more design possibilities. In addition to aiding the educational experience of university students involved in part testing, this project will ultimately result in the creation of U.S. manufacturing jobs for the mass production of ceramic and metal bonded parts.


The intellectual merit of this project is to utilize and greatly expand upon the findings of impact bonding dissimilar metals from previous bodies of work to advance the scientific understanding of how ceramics impact bond to metals and how these bonded joints survive or potentially degrade when undergoing intense impact fatigue cycle testing. Although fatigue cycle testing on metal/ceramic interfaces has been documented when the joint is formed through other methods, the PI and team seek to perform fatigue cycle testing when metal/ceramic interfaces are optimized for strength and durability by the use of near net-shaped impact bonding. Previous methods of attaching ceramics to metals have been limited to brazing and adhesives, each of which is limited by temperature and strength. Other mechanical methods of joining ceramics and metals will simply not hold up during impact fatigue cycling due to the different compression properties of the joined materials. This project aims to produce pioneering publications on impact bonding ceramics and metals and will also further enhance the knowledge of high velocity impact bonding systems. Of particular interest is the impact bonding of ceramics/composites such as tungsten carbide to hardened steel because of immediate industrial applications.

A method of controlling actuation of a flush apparatus includes the steps of configuring a control module to actuate the flush apparatus for completing a flushing cycle periodically; and after a given unused time period of the flush apparatus, enabling the control module to enter into a sleep mode to stop an actuation of the flush apparatus. Therefore, during the rush hours, the control module is configured to actuate the flush apparatus frequently and during the off rush hours, the control module is configured to actuate the flush apparatus seldom.

This Small Business Innovation Research (SBIR) Phase I project seeks to advance manufacturing processes in the dissimilar metal/impact welding industries via an aluminum/water reaction that chemically produces hydrogen energy. Ideally, the energy in the form of about 100 kpsi-200 kpsi, could be the source of power for a small high-velocity impact bonding machine to metallurgically bond dissimilar metals. Current impact bonding methods such as explosive welding have not led to machines for bonding near-net-shaped parts, but rather a process of preparing large raw materials to be cut into the desired smaller parts. Disadvantages associated with explosives include safety issues, long lead-times, high costs, material waste, and reliance on imports. A high-velocity impact bonding machine could revolutionize the manufacturing of smaller, discrete parts opening new avenues for design engineers. Experiments will be conducted to establish the ideal conditions for impact induced interlocking micro-bonds, e.g., between Copper and Stainless Steel. The variable test parameters of this project include: (a) flyer velocity (implicitly determined by hydrogen pressure), (b) impact angle between the flyer plate and the anvil or base material, (c) standoff distance between flyer and anvil material, and (d) surface topography. The results will lead to optimized conditions for wavy-joint morphology of dissimilar metals The broader impact/commercial potential of this project is attributed to the utilization of a new energy source that will transform how some manufacturing processes are powered. The advancement of an aluminum/water reaction to replace explosives or complex pressure, heat or electrical sources for electrical, friction, heat or impact bonding methods of manufacturing dissimilar metal components will prove to have many benefits by developing a safe, user-friendly and environmentally-friendly bonding machine. Additionally, impact loading for other processes such as forging and hydroforming that use high pressure fluid will capitalize on these benefits as well. The introduction of this machinery will provide a versatile assembly-line manufacturing capability with advantages to include: (a) substantial cost savings, (b) motivating small U.S. manufacturing companies to produce discrete parts within the U.S., (c) potential for new designs of customized parts otherwise infeasible, (d) a low skilled operation for small facilities eliminating long lead-times, and (e) the potential for other manufacturing processes that could use this platform technology. Dissimilar/bi-metallic parts are in high demand in the chemical, automotive, aircraft, marine, and nuclear industries due to their high conductivity and galvanic corrosion resistance and favorable mechanical properties contained in one part.

A driving mechanism of a flush apparatus includes a motorized unit supported by a valve body, a plunger arm driven by the motorized unit for operating the valve body between a sealed position to an unsealed position, and a timer module operatively linked to the motorized unit to set a flush interval for enabling the flushing operation to be completed once every flush interval. The driving mechanism converts the flush apparatus into water efficient fixture by controlling the amount of daily flushes for ultimate water efficiency.
