The mechanical properties and corrosion resistance of 316 L stainless steel fabricated using the Laser Engineered Net Shaping (LENS) technique have been studied. The crack-free, full density samples made using SS316L alloy powder and the LENS technique are ...
Since the early of the 19th century, canning is one the most efficient ways to preserve foods. Tinplated steel has been used since the beginning for this purpose and it is still one of the most used materials for cans production because it combines the goo ...
Total hip joint arthroplasty is a medical procedure to replace a natural failed joint by an artificial joint to improve the quality of life of the patient. In spite of its broad success, there is a concern about the relation between the presence of modular ...
Thermoplastic polymer composites (TPC) with multiple fabric layers of continuous fiber reinforcement are laminate sheets designed to be thermally stamped and overmolded leading to low cycle times and thus high volume composite parts. Injection over-molding ...
The mounting bolt of helicopter main gearbox support strut was fractured into two pieces during the flight mission. The fracture occurred at the root of the first engaged thread of the bolt-nut assembly. Visual inspection of the fracture zone revealed crac ...
This paper addresses radio frequency identification (RFID) authentication and ownership transfer in offline scenarios. Four typical related works are reviewed in detail. A series of shortcomings and vulnerabilities of them are pointed out. A new RFID authe ...
Normal micro-movements at the bone-implant interface originate fretting-corrosion processes, thus releasing wear debris from the bone and metallic devices and compromising the fixability of the implant. Titanium aluminum nitride (Ti1-xAlxN) coatings have b ...
Al-Cr-Fe complex metallic alloys are new intermetallic phases with low surface energy, low friction, and high corrosion resistance down to very low pH values (0-2). Flow microcapillary plasma mass spectrometry under potentiostatic control was used to chara ...
User authentication is an important step to protect information, and in this context, face biometrics is potentially advantageous. Face biometrics is natural, intuitive, easy to use, and less human-invasive. Unfortunately, recent work has revealed that fac ...
The present work focuses on stress-corrosion mechanisms in soda-lime silica glass. Four-point beam-bending tests were performed on small specimens, measuring failure time in function of temperature and relative humidity. By using linear elastic fracture me ...
