MAIN ACHIEVEMENTS

Successfully researched and manufactured several types of tungsten-based alloys for industrial applications. WC-Co hard alloys obtained the Vickers hardness larger than 1500 HV30 and a fracture toughness, K1C, reaching values of above 12 MPa.m1/2, have been applied as N75 rotary percussion bridge drill bits with a total drilling depth of over 500 m. WC-Ni hard alloys achieved the Vickers hardness > 1100 HV30, fracture toughness greater than 22 MPa.m1/2 and many superior properties are being tested in application. These projects were done by Prof., Dr. Doan Dinh Phuong et al. and won the Tran Dai Nghia Award in 2019.
In recent years, the Advanced Metallic Materials Laboratory has developed various nitride-based coatings derived from transition-metal Ti systems, including TiN, TiAlN, TiAlCr, TiAlBN, and TiAlVN, deposited on WC–Co hard alloys and titanium-based alloys. From these studies, the group has fabricated nitride coatings exhibiting the following characteristics: hardness > 20 GPa (TiN) and > 35 GPa (TiAlN, TiAlXN), friction coefficient < 0.6, and coating thickness in the range of 1.5–2 µm. The Laboratory is also actively developing coating systems capable of operating under extreme conditions high temperature, corrosion, and wear targeting applications in turbine engines and components for the security and defense sectors.
Successful fabrication of copper heat pipes with porous capillary structures, exhibiting an effective thermal conductivity of > 10.000 W/m.K. Heat-sink modules for 200 W and 500 W LED systems using the developed heat pipes have met all required technical performance criteria. This research was conducted in collaboration with Rang Dong Light Source and Vacuum Flask Joint Stock Company and continues to be further developed for practical implementation.
