Summary: The influence of dilution on the high-temperature-high-vacuum-friction behavior of Ni-Cr-B-Si coating made on AISI 316L (N) stainless steel using plasma transferred arc welding process is investigated. Two coatings with different dilution levels were produced by varying the welding current. The increase in dilution led to a change in microstructure from hypereutectic to eutectic, as well as variations in the distribution and relative contents of borides and carbides. Sliding wear tests were conducted at 823 K under a vacuum of 10(-5) mbar using SiC ball as the counterbody.

Summary: This study compared hardfacing techniques using different welding methods for coal crushers. It was found that low-heat input welding processes resulted in less dilution and more martensite and austenite in the microstructures of the hardfacings. Single-layered hardfacings with more alloying elements showed lower hardness and poorer wear resistance compared to three-layered hardfacings.

Summary: Ti and Ti-based alloys are commonly used in aerospace and automotive components, but face challenges in wear resistance at elevated temperatures. The study found that Ti-xTiC composite coatings exhibit improved friction and wear performance compared to baseline Ti coatings, with Ti-35%TiC showing the best overall performance at 575 degrees C. The tribological behavior was attributed to the formation of stable oxide layers on the wear surfaces containing TiO2, WO3, and CoWO4.

Summary: Aluminized coatings play a crucial role in enhancing process efficiency at higher operating temperatures for Ni based alloys. This study compares Pd-modified and unmodified aluminized coatings with Pt-modified coatings to understand their formation mechanisms and oxidation performance. Results reveal that Pd reduces the diffusion of Al during coating formation, enhances outward diffusion of Ni, and decreases alloying element (Cr and Ti) diffusion into the intermetallic layer. On the other hand, Pt increases Al diffusion and mobility in the intermetallic layer. These characteristics directly affect oxidation at 1000 degrees C, with Pd reducing the transformation rate of theta-Al2O3 -> alpha-Al2O3, resulting in a higher void density at the beta-(NiAl)/theta-Al2O3 interface, oxygen diffusion into the coating, spalling, and faster degradation of coatings.

Summary: One of the main advantages of additive manufacturing is the ability to build components of different sizes and geometries through the layer-by-layer deposition process. However, for alloys like duplex stainless steels, the control of microstructure is challenging due to the heat cycles and heat input from successive layers. This manuscript reviews the main features of duplex stainless steels processed by additive manufacturing processes, with a focus on directed energy deposition. The impact of thermal cycles and post processing heat treatment on the microstructure is discussed, along with results obtained from different additive processes.

Summary: The joining of stainless steel and copper is challenging due to their differences in melting temperatures and thermal conductivities. This study investigated the joining of 316L stainless steel and copper using high velocity oxyfuel. It was found that 316L coatings have better adhesion to copper substrates compared to copper coatings on AISI 316 substrates. The ease of 316L incoming particles to embed in the softer copper matrix and the higher susceptibility of 316L coatings to diffuse into copper substrates contribute to the superior adhesion.
