RISWear Mechanisms of Gray Cast Iron in the Presence of Environmentally Friendly Hydrofluoroolefin Based Refrigerant and the Effect of Tribofilm Formation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydrofluoroolefinbased refrigerant (2,3,3,3tetrafluoropropene, namely, HFO1234yf), which has been developed as an environmentally friendly refrigerant, is proposed as a direct replacement solution in automotive airconditioning ...
Rough Surface Normal Nanocontact Stiffness: Experimental Measurements and Rough Surface Contact Model Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents experimental contact stiffness measurements for various thin films as well as homogenous materials through pressing a flat punch onto a nominally flat rough surface. These materials are typically used ...
Yield Maps for Single and Bilayer Thin Films Under Scratch
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite element (FE) simulations were performed to study yielding in single and bilayer (BL) film systems using a “yield zone map†approach. Onset of yielding was observed at the interface, substrate, surface, and film ...
Exploring the Impact of HFO-1234YF Refrigerant on the Tribological Properties of Advanced Polymeric Coatings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The global focus has shifted toward mitigating the impact of global warming, particularly in the air-conditioning and refrigeration sectors, where there is a strong emphasis on the use of environmentally friendly refrigerants. ...
Wear Modeling of Nanometer Thick Protective Coatings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Use of nanometer thin films has received significant attention in recent years because of their advantages in controlling friction and wear. There have been significant advances in applications such as magnetic storage ...
