Abstract
The present invention provides a treated projectile having a reduced friction compared to an untreated projectile comprising: a projectile comprising a higher atomic concentration of Ca and a reduced friction in the treated projectile than a comparable untreated projectile.
Claims6
A method of reducing the friction between a projectile and a barrel comprising the steps of:
- providing a projectile;
- treating the projectile to reduce the friction of the projectile when discharged, by contacting the projectile with a solution to form a treated projectile having,
- an atomic Ca concentration of about 20 percent,
- an atomic C concentration of about 65 percent,
- an atomic O concentration of about 10 percent, and
- an atomic Fe concentration of about 3 percent dispersed within at least a portion of an interior portion of the treated projectile, wherein the treated projectile reduces the friction of the treated projectile when compared to an untreated projectile;
- providing a cartridge comprising a body having a propellant chamber at least partially filled with a propellant, a primer, and a projectile aperture;
- and inserting the treated projectile into the projectile aperture.

A method of increasing the life of a gun barrel comprising the steps of:
- providing a cartridge comprising a treated projectile treated to reduce the friction of the projectile when discharged, wherein the treated projectile has,
- an atomic Ca concentration of about 20 percent,
- an atomic C concentration of about 65 percent,
- an atomic O concentration of about 10 percent, and
- an atomic Fe concentration of about 3 percent dispersed within at least a portion of an interior portion of the treated projectile, wherein the treated projectile reduces the friction of the treated projectile when compared to an untreated projectile;
- the cartridge comprising a body having a propellant chamber at least partially filled with a propellant, a primer, and a projectile aperture;
- and the treated projectile inserted into the projectile aperture, wherein the treated projectile has a reduced friction with the gun barrel compared to an untreated projectile thereby increasing the life of the gun barrel.
