As almost any prosperous industry, ultrasonic cleaning doesn’t stand still – the engineers are grinding away to integrate new methodologies and approaches into practice. Mentioned below is the list of noteworthy technologies that are not yet integrated on industrial level.
Reduced friction between the surfaces
An imposition of ultrasonic vibrations on the mating surfaces to reduce friction arising between them is an effect that can be used in the assembly of main units in which the parts are assembled with an interference, as well as to reduce scuffing and scratching of the surfaces of the mating parts.
A reduction in friction with the help of ultrasound has been successfully demonstrated in industrial trial installations of fuel rods in the fuel assembly skeleton. The trials show that the friction is reduced by 3-4 times.
Also, for example, an application of ultrasonic vibrations to the walls of the crystallizing dish reduces the friction, having a positive effect on the surface quality of the workpiece, reduces wear of the crystallizing dish surfaces (copper or graphite plates and bushings), plus considerable energy savings are achieved due to load reduction on engine.
Free-flowing materials sealing and compressing
Ultrasound promotes densification of free-flowing materials. This property can be used effectively to seal the powders during their compaction. Due to this, the molded product acquires a more uniform structure and its internal defects (cracks and sink) are eliminated, while the level of hardness is increased.
Metal parts hardening
Metal parts hardening by means of ultrasound, where protrude steel balls with a diameter of 0.4 to 2 mm act as reinforcing elements is another reasonable processing method. An ultrasonic transducer transmits pulses to the balls that make them move randomly within a specific hub and strike the surface of the part subjected to hardening with high frequency.
The method is utilized for aluminum, cadmium, iron, zinc, bronze, graphite and many other alloys production. For example, mixing aluminum with lead improves the processability of the aluminum molding.
