Spark Plasma Sintering of NiCrSiBC Alloys

, 2023
Nickel-based alloys of the NiCrSiBC system (colmonoy alloys) are normally deposited on stainless-steel substrates for coating applications, once they present high resistance to wear and corrosion at high temperatures. Typically, deposition occurs through welding processes, such as PTA (plasma transferred arc) or laser cladding.

Dual‐Salt Carbothermal Shock Strategy Enabling Ultrafast and Sustainable Regeneration of Spent LiFePO4 Cathode Materials

Advanced Functional Materials, EarlyView.
Lithium iron phosphate (LFP) accounts for over 50% of the global cathode market, underscoring the need for efficient recycling and regeneration. We propose a dual‐salt carbothermal shock (CTS) strategy using LiI and NaI to in situ repair Li vacancies.

In Situ Crystalline‐Amorphous Composite Oxide Structure Suppressing Thermal Wear Instability for Refractory Multi‐Principal Element Alloy

Advanced Functional Materials, EarlyView.
An effective strategy is developed to overcome the medium temperatures wear resistance degradation in refractory multi‐principal element alloys. By utilizing chemical short‐range ordering to trigger oxygen‐induced amorphization, a composite oxide structure is formed, which combines high hardness with robust stiffness.
