Field is widely used.
Damping alloy can be divided into aluminium base damping alloy, iron-based damping alloy for parent metal, and magnesium-based damping is closed
Multiple kinds such as gold and copper-manganese base damping alloy.Wherein, the damped coefficient of copper-manganese base damping alloy is other with differing substantially from
The relationship of the characteristics of damping alloy kind, i.e. damping capacity and frequency are little, and are only clearly dependent on the amplitude of vibration.Thus
In actual use, copper-manganese damping alloy can carry out effectively vibration and noise reducing in the range of multiple frequency bands.From world's model
From the point of view of enclosing, copper-manganese damping alloy is worldwide had been widely used.
Copper-manganese damping alloy according to manganese content therein can be divided into high Mn content manganin, and (Mn content is greater than
70wt.%), (Mn content is small for middle manganese content manganin (Mn content is located at 60-70wt.%) and low manganese content manganin
60wt.%).What is be most widely used at present is high Mn content manganin and middle manganese content manganin.In practical vibration and noise reducing
In use, copper-manganese class damping alloy need and a variety of alloy base materials coupled.For example, in the vibration and noise reducing process of lathe
In, it needs to carry out such alloy into the coupling on mechanics by suitable mode and lathe base.Wherein, the pedestal one of lathe class
As be all have with good damping characteristic cast-iron alloy preparation.
Make us feeling regrettably, it is general for the use of copper-manganese class alloy by the way of riveting at present, rather than it is logical
The welding often thought.Welding material between copper-manganese damping alloy and cast iron is had not been used in international coverage.Generally in reality
It is middle to be welded using master alloy as welding material.But even if the welding form protected using argon gas, can also generate bright
The oxidation of aobvious degree and the oxide for making welding point metallurgical type occur is mingled with.This tissue defects occurred within a fitting
Apparent embrittlement occurs for the connector after can making welding.Apparent stress corrosion and cracking can occur in use, drop significantly
Low damping alloy is in deformation process to the ability of energy dissipation.
In view of the most vibration source of industrial circle is to be made of cast iron, thus develop a kind of for high Mn content copper-manganese
Welding material between damping alloy and cast iron has very important realistic meaning for industrialized mass production.Either from
It is all one of the pressing issues that our times various countries need to solve for the angle or industrialization development demand of technical research.
