Copyright UCT Defense LLC, 2003 Page 7 UltraCem TM (5th generation) provides increased hardness and wear resistance while providing a high level of lubricity. Cubic inch density is greatly increased resulting in higher shear strength. (Magnification 500x) Evolution of Nickel-Boron Earlier generations of Nickel-Boron coatings had a high degree of voids, leading to reduced corrosion resistance and sheer strength.
