The extremely sharp and smooth enough neat cutting edge machining to have a specific, smooth shape, and edge rounding mostly waterfall edge, this process is called edge passivation. tungsten carbide cutting tool edge passivation change the contours of the cutting edge and morphology, but also to improve the microstructure of the blade surface area, thereby affecting the cutting process, tool performance and workpiece quality. tungsten carbide cutting tool edge passivation impact, affecting mainly the following aspects: the distribution of cutting temperature, the size distribution of cutting force, stress and strain, and chip formation and chip flow, deformation region of the workpiece, the workpiece surface integrity (residual stress), the machined surface roughness, surface hardening process and tool wear resistance.

Edge passivation tungsten carbide cutting tools for working efficiency has an important role in the following cases generally require the tool edge passivation:
1. The new sharpening of tungsten carbide cutting tools or regrinding of tungsten carbide cutting tools.
2. Prior to the tungsten carbide coating.
3. When the impact of heavy-duty cutting or cutting edge tungsten carbide cutting tools needed to passivation.

High quality tungsten alloy penetrator is an important symbol of national materials technology development, but also an important material for high performance kinetic energy penetrators, which will be related to the development of standards to improve our standard of weapons and equipment needed can win a local war.

To this end, it should address some of the issues and the actual needs of the existing one hand, vigorously strengthen the management and coordination of military material development project, on the other hand should further improve the scientific management level of research institutes and universities to form a kind of systematic and highly complementary mechanism, and created a high standard of professional research team, in order to promote China's missile tungsten alloy materials technology to develop low-input, high output, high standards and high availability of direction. And should strive to achieve a breakthrough in the short term in some key technologies in order to be able to significantly improve the overall performance of armor-piercing tungsten alloy material.
