In both defense and heavy engineering industries, gears, threads, and tooling are exposed to severe operating conditions, including high friction, thermal stress, and corrosive environments. Conventional protective measures often fail to ensure the required operational longevity, leading to premature wear, frequent replacements, and costly downtime.
Barrel wear and abrasion represent one of the most persistent problems in grenade launchers and other large-caliber weapon systems. Without advanced protective measures, barrels degrade quickly under extreme firing conditions, reducing accuracy, increasing maintenance costs, and requiring frequent replacement.
Military and heavy-duty vehicle engines operate in extreme environments where conventional oils and greases are insufficient to prevent wear, cold-start difficulties, and premature breakdown. Vehicle downtime due to engine degradation leads to higher operational costs, reduced reliability, and mission delays.
Improved anti-friction and anti-wear characteristics of optical/aiming mechanisms
For this testing, lead bullets LRN 10.2 g, caliber 38 (.3575) were pre-treated. Bullets were coated with ultra-thin layers of fullerene nanoparticles of tungsten disulfide, without affecting the caliber.
In the first application cycle, an anti-friction, anti-wear, heat- resistant, and anti-corrosion Nanotechnology-based agent was used, which significantly extended the service life of cutting tools by 42%–120%.
