Teflon-coated bullets are handgun bullets that have been covered with a coating of Teflon to reduce barrel wear. Molybdenum disulfide is also sometimes used as a coating.
In the 1960s, Paul Kopsch (an Ohio coroner), Daniel Turcos (a police sergeant), and Donald Ward (Kopsch's special investigator), began experimenting with special purpose handgun ammunition. Their objective was to develop a law enforcement round capable of improved penetration against hard targets, such as windshield glass and automobile doors. Conventional bullets, made primarily from lead, often become deformed and less effective after striking hard targets, especially when fired at handgun velocities. The inventors named their company "KTW," after their initials.
After some experimentation with steel rounds, the officers settled on a brass core. Unlike lead, which is relatively malleable, brass wore out barrels far more quickly than normal jacketed rounds, since the brass did not reform to fit the rifling. This is one reason the bullets were then coated with a layer of Teflon to reduce barrel wear. The inventors had also noted that canes were frequently tipped with the relatively soft Teflon to help them grip surfaces. They expected that coating the bullets with Teflon would reduce dangerous ricochets when fired through vehicle doors and windows.[1]
In 1982, NBC ran a special on the bullets and argued that the bullets were a threat to police. Gun control organizations in the U.S. labeled Teflon-coated bullets "cop killers" because of the supposedly increased penetration the bullets offered against ballistic vests, a staple of the American police uniform. Supporters of gun control believed that the Teflon coating was responsible for this increased penetration[2] despite the fact that the material is only an outer coating for the brass penetrator and usually peels off during its trajectory through the air.
The federal ban on armor-piercing ammunition uses only the composition of the bullet's core to determine legality.[3] However, many states have legislation restricting various kinds of coating materials. For example, South Carolina state law specifically bans "ammunition or shells that are coated with polytetrafluoroethylene (Teflon)".[4]

特氟龙(铁氟龙)涂料是一种独一无二的高性能涂料,结合了耐热性、化学惰性和优异的绝缘稳定性及低摩擦性,具有其他涂料无法抗衡的综合优势,
1、不粘性:几乎所有物质都不与特氟龙涂膜粘合。很薄的膜也显示出很好的不粘附性能。
2、耐热性:特氟龙涂膜具有优良的耐热和耐低温特性。短时间可耐高温到300℃,一般在240℃~260℃之间可连续使用,具有显著的热稳定性,它可以在冷冻温度下工作而不脆化,在高温下不融化。
3、滑动性:特氟龙涂膜有较低的摩擦系数。负载滑动时摩擦系数产生变化,但数值仅在0.05-0.15之间。
4、抗湿性:特氟龙涂膜表面不沾水和油质,生产操作时也不易沾溶液,如粘有少量污垢,简单擦拭即可清除。停机时间短,节省工时并能提高工作效率。
5、耐磨损性:在高负载下,具有优良的耐磨性能。在一定的负载下,具备耐磨损和不粘附的双重优点。
6、耐腐蚀性:特氟龙几乎不受药品侵蚀,可以保护零件免于遭受任何种类的化学腐蚀。
铁氟龙广泛应用于耐高温、要求搞粘性的行业。
哇塞,难道说楼主是军事部长?
我觉得应该打不穿,防弹衣毕竟是防弹的,如果只是涂上了铁氟龙这种廉价(对于国家来说是廉价)的材料,防弹衣就没用了,世界上就不会有防弹衣了。。只不过涂上了铁氟龙的子弹具有更好的滑动性,可以减少摩擦阻力,使子弹更具穿透力
是的,会使威力小幅度提升,因为涂上了铁氟龙后,增加了它的滑动性,减小阻力,从而起到增大速度的作用,在高速运动的情况下,会使子弹威力增加~frim百度知道作者416697600
简单说就是变猛了。。。
你装什么装
涂料特富龙就不粘锅了嘛。
这贴为什么不火!!!
对于英语盲来说,等于没扫
对于英语退化了的楼主来说,等于没扫。。。
