It really does not matter how well gears are created and manufactured because gear corrosion or pitting can occur that may easily end up in catastrophic failure. Gray staining or micropitting is a common failure mechanism used in burdened cases of carburized gears. The conventional FZG gear test is what is usually used to figure out the micropitting load capacity of gear lubes. Recently, FZG gear testing has shown its effectiveness for evaluating the effect of superfinishing on raising a gear's micropitting load capability.

What's even worse is that micropitting may very easily go undetected. Regular visual examination often fails to reveal deterioration. The following may be present: pitting deterioration, and intergranular assault (IGA). It is believed that superfinishing is better at repairing corrosion as compared to glass beading because superfinishing can help slow down the progress of IGA and pitting deterioration.

One of the most powerful systems capable of raising the load capability of gear flanks is called superfinishing or metal refinishing and this is proven by study results. Some producers use a one of a kind and trademarked procedure that is capable of generating a non directional low Ra surface called the Isotropic Superfinish or ISF. It employs mass finishing equipment in conjunction with accelerated refinement chemistries that are non-hazardous and environmentally friendly.

The bottom line is ISF is a process that is not typical and the only procedure capable of producing a non directional low Ra surface. It utilizes mass finishing devices in combination with accelerated refinement chemistries that are non-hazardous and eco friendly. ISF systems can be a powerful answer for increased quality, volume, and reliability of metal finishing processes. Reduction in friction and wear, improved deterioration resistance, and improved part durability are just some of the advantages from having an ISF metal refinishing. You can use this procedure in several sectors like aerospace, medical, military, automotive, off-highway, power generation, motor sports, and of course gearing and bearings.

There is a component generally used in metal refinishing recognized as vibratory bowl finishing which can be utilized to superfinish the surfaces of contrasting elements to an isotropic finish when using nonabrasive, high-density media in combination with an isotropic superfinishing chemistry. Friction is decreased with the use of this method because it increases the energy and motion transfer efficiency within the metal contact area.

USF metal refinishing services can also be advantageous because you do not have to be concerned about capital investment, added staffing, waste management, quick turn around time, technical support, and of course long term flexibility. The advantages include cost saving and a significant decrease in wear ensuing in longer component life, lower lubricant temperature ranges, increased fuel economy, and reduced operating expenses.
