描述了CVD金刚石的四个新应用实例。每种应用:金刚石燃料喷嘴；钻石文丘里旋流器；金刚石X射线靶和金刚石雷达罩在金刚石生长、附着力和最终制造方面具有独特的挑战。通过本文详细描述的策略，已成功满足这些要求。在每一种情况下，钻石的一个或多个最高级的物理或化学属性都被用来实现对系统的预期效果。其中包括硬度、模量、耐磨性、耐磨性、导热性、电阻、光谱透明度、低发射率、低摩擦系数和耐化学性。

FOUR EXAMPLES OF NEW APPLICATIONS FOR CVD DIAMOND ARE DESCRIBED. EACH OF THESE APPLICATIONS: DIAMOND FUEL NOZZLES; DIAMOND VENTURI SWIRLERS; DIAMOND X-RAY TARGETS, AND DIAMOND RADOMES, HAS UNIQUE CHALLENGES IN DIAMOND GROWTH, ADHESION, AND FINAL FABRICATION. THESE HAVE BEEN SUCCESSFULLY MET THROUGH STRATEGIES DESCRIBED IN DETAIL IN THIS PAPER. IN EACH OF THESE CASES, ONE OR MORE OF DIAMOND'S SUPERLATIVE PHYSICAL OR CHEMICAL ATTRIBUTES ARE EMPLOYED TO ACHIEVE THE DESIRED EFFECT ON THE SYSTEM. THESE INCLUDE HARDNESS, MODULUS, WEAR RESISTANCE, ABRASIVENESS, THERMAL CONDUCTIVITY, ELECTRICAL RESISTANCE, SPECTRAL TRANSPARENCY, LOW EMISSIVITY, LOW COEFFICIENT OF FRICTION, AND CHEMICAL RESISTANCE.
