Improve on Corrosion Resistant Surface for AISI 4140 Steel Coated with VN and HfN Single Layer Films

International Journal of Electrochemical Science, 2013
To improve the corrosion resistance of different industrials application, we studied vanadium nitride (VN) and hafnium nitride (HfN) single layer thin film, which were deposited onto Si (100) and AISI 4140 steel substrates via r.f.

Tribological Analysis of Laser-Cladded Martensitic and Mixed-Alloy Coatings: Correlating Microstructure, Hardness, and Wear Response

Journal of Manufacturing and Materials Processing
High-strength quenched and tempered steels such as EN 42CrMo4, widely used for marine shaft applications due to their high strength, toughness, and fatigue resistance, are nevertheless susceptible to surface degradation under severe dry sliding ...

The Optimization of Severe Shot Peening Coverage for Enhanced Fatigue Performance of AISI 4140 Steel: A Combined Experimental and FE-Cell Approach

Journal of Manufacturing and Materials Processing
Shot peening is widely used to improve fatigue performance by introducing compressive residual stresses, but the influence of very high coverage levels on medium carbon steels such as AISI 4140 remains unclear.
