“…Based on Young's equation, the contact angle of melting brazing alloy on the sample surfaces could be calculated by the interface energy of solid-liquid, liquid-gas, and solidgas [23]. The modification layer on the substrates, such as Ni [24], Au [25], Cu coatings [26], etc., can improve the wetting properties of the brazing alloy via change of the solid-related Coatings 2022, 12, 1328 2 of 15 interface energy. Considering the cost and the compatibility between Fe and Ni elements, the Ni coating is always prepared as the modification layer on the stainless steel [27][28][29].…”

The wetting properties of the brazing filler on the substrates play an important role in achieving a reliable joint. In this work, the wetting behaviour of the Mn-based brazing alloy on the surface of 1Cr18Ni9Ti stainless steel is investigated. First, surface treatment was adopted to prepare four different surface states on the stainless steel, including polished, acid treatment, nickel coating, and sandblasting. The surface morphology with nickel coating shows micro-and nano-scale protrusions, forming a uniform 3D Ni layer. The surface roughness of substrates increases after sandblasting treatment. It is found that the wetting angle of brazing alloy on the Ni coated substrates decreases noticeably. After sandblasting, the high roughness speeds up the wetting spread of the brazing alloy at the initial stage. The effect of heating temperature and holding time is also studied systematically. With the increase in holding time, the height of the melting brazing alloy decreases slightly on the sample surfaces. Based on the characterization of the joint section, the Ni layer dissolves into the melting brazing alloy. The diffusion and dissolving are indicated between the brazing alloy and substrates, forming a reliable bond.

“…316 H stainless steel electroplated with copper coatings was used in a molten salt reactor [14]. Carbon steel coated with copper for furnace brazing, due to the good thermal conductivity of copper, could be used as a structural material in a heat exchanger [15]. An innovative surface coating made of zein, bioactive glass, and copper containing bioactive glass was used as an antibacterial, proangiogenic and pro-osteointegrative coating on stainless steel implants [16].…”

This research deals with the deposition of copper on a steel substrate. Two different methods were investigated: electrochemical and magnetron sputtering. The deposition parameters were optimized to obtain a coating layer with uniform granular structure and good adhesion to the substrate. As a novelty, carbon nanowalls (CNW) were used as reinforcement in copper coatings on the steel surface. The morphology of the coatings, adhesion and Vickers microhardness were performed to emphasize the CNW influence on the coating properties. Open circuit potential and Tafel analysis were used for electrochemical characterization. These kinds of CNW-copper composite with improved hardness and adhesion and surface electrical resistance around 1 Ω·cm could have miscellaneous applications in different domains such as aerospace, electronics, automotive and power-generation.

“…Diffusion has been shown to play a major role in the creation of layers. Industrial applications of such coatings can be applied in heat transfer devices because of the good thermal conductivity of copper [16]. Brass and copper alloys offer high strength and excellent strength retention at high temperatures.…”

The objectives of this research is to investigate the tensile strength and structure of metallography of the metal connection between aluminum and brass by the brazing method. The type of joining is the but joint using an alusol filler. Specimens were made according to ASME IX standards. The ASTM E8 standard was used to tensile test. The macro and micro photos was carried out using ASTM E407-07. A joint with a shear area of 350 mm 2 was broken when pulled with a load of 4.410 kN. The highest stress, strain and Young modulus was 12.601 N/mm 2 , 0.11 and 1.183 kN/mm 2 respectively. The porous microstructure was seen in the weld area facing to the brass material. The chemical composition of the specimens consisted of C 21.53%, Al 2 O 3 37.20%, CuO 13.63%, and ZnO 27.64% from the EDX results.
