Compared with other bronzes, aluminum bronze has better mechanical functions, wear resistance, corrosion resistance, heat resistance, and non-magnetic. The spraying conditions are: spraying voltage 35 V, spraying current 120 A, spraying interval 150 mm, atomizing air pressure 0. After the Neophot large-scale optical microscope and the S-2700 electron scanning microscope, the arrangement and structure of the aluminum bronze coating and the spray particles were studied. test.
The base material is Copper strip for disconnect connection steel and the spraying material is \u0026Phi;3 mm aluminum bronze welding wire QA19-2. Test equipment and materials Plasma spraying uses SAS-1 supersonic arc spraying equipment developed by the Second Artillery Engineering Institute for spraying.Aluminum bronze is an alloy of aluminum and copper.
Therefore, for plexiglass products, people choose plasma spray, flame spray, arc spray technology to spray aluminum bronze powder or wire as a soft support surface, hard surface wear, anti-cavitation working layer, and even in order to improve other The bonding strength of the coating and the steel and cast iron substrates, using the aluminum bronze coating as the # bonding bottom layer of the arc spray coating. The aluminum bronze coating not only has outstanding wear resistance and corrosion resistance,
but also has outstanding resistance to fretting wear. The Micromet II hardness tester and the Instron1195 electronic tensile tester were used to test the bonding strength of the aluminum bronze coating.7 MPa. The aluminum bronze coating will be used as an anti-fretting and anti-adhesive wear coating for engine parts, water pump impellers, pistons, and bronze castings. With the rapid development of the aerospace industry, thermal spray coatings such as wear resistance, heat insulation, and sealing have been widely used on gas turbine engine parts
If it is a heat-treated alloy, it must be cooled slowly from the soft-burning temperature to completely avoid the quenching effect. T7: After the solution treatment, the temperature or time of the artificial aging treatment is higher or longer than that of the T6 treatment. T61: After solution treatment, it is treated with warm water quenching and then artificial aging treatment. The intention of artificial aging treatment is to improve the mechanical properties of the material and the stability of the scale.
