“…Dobrą przewodność elektryczną można uzyskać stosując połączenie metaliczne uzyskane w procesie lutowania miękkiego. Lutowanie grafitu w sposób bezpośredni jest jednak niemożliwe do wykonania z uwagi na brak jego zwilżalności lutami miękkimi [9,10].…”

“…Aluminium surface is covered hermetically by a high-melting (2050 o C) and chemically resistant (11,163 kJ/mol O 2 ) layer of oxides Al2O3. It has low mechanical characteristics, particularly over 500 o C. Strong thermal conductivity (237 W/m K), significant volume contraction (7%), and high thermal expansion (26x10 -6 K -1 ) all contribute to the development of thermal stresses and deformations [9].…”

Since hard metals are among the materials that liquid brazing alloys scarcely adhere to, they should not be brazed without first removing the surface layer after sintering. The electrolytic etching method, which gives the surfaces of materials that are hardly wettable very good energetic qualities, is given specific attention. Deep etching is done by using a high concentration of acid solution to roughen the surface. Both dry and wet settings are suitable for etching. An etching fluid is used for etching in a wet environment. Typically, the plate or metal is submerged in an etching solution, where the substance is chemically broken down. While in dry etching, the plasma’s gas phase is where the etching takes place. Due to the presence of plasma in this situation, the etching process that takes place combines chemical and physical processes. Plasma etching is another name for dry etching. Deep etching is an etching process to obtain a rougher surface. Wet deep etching requires a longer immersion time and even several immersions are required. The purpose of this study was to determine the effect of etching treatment in the brazing process of Aluminium-Mild steel for its microstructure and mechanical properties. The specimens in this study used aluminium 6000 series, mild steel, Alusol ER4043, and etching fluid. Mild steel surfaces are deep etched before brazing. Specimen manufacturing standard refers to ASTM D1002. A micro photo test was conducted to compare the surface conditions of aluminium and mild steel with and without etching treatment. The deep etching process is carried out in three variations of time, namely 20, 30, and 40 minutes. The results showed that the tensile strength increased with deep etching treatment on the surface.

To reduce the weight of a vehicle and improve its fuel efficiency, it is preferable to produce its body in aluminium in place of steel. However, designs may require hybrid structures of aluminium and steel, and there remains a challenge to make a sound bond between the two metals due to their differences in physical, mechanical and metallurgical properties. In the present work, the effect of a zinc coating on the diffusion behaviour between liquid aluminium and a steel substrate was studied. A cost-effective overcasting process was used to cast commercially pure aluminium around uncoated mild steel and 20 µm thick zinc coated steel samples. A reaction layer of similar composition and crystal structure was found between the aluminium and the steel in both cases. SEM-EDS characterisation showed that the reaction layer consisted of 73 at.% aluminium and 28 at.% iron. Moreover, EBSD analysis confirmed that the reaction layer corresponded to the Al13Fe4 phase. The thickness of the reaction layer increased with the presence of the zinc coating as compared to uncoated steel sample. The reason for enhanced reaction layer thickness is believed to be caused by improved wetting of molten aluminium on the zinc coated steel.
