Description
Technical field
Molybdenum group glass/kovar alloy Laser Welding side is connected by addition Mo-Mn-Ni middle layer the present invention relates to a kind of
Method belongs to nonmetallic and metal material interconnection technique field.
Background technique
Glass material has the characteristics that high intensity, high hardness and corrosion resistance, excellent insulation performance, but the low of glass itself is prolonged
Malleability and poor impact flexibility limit its application in engineering.Thus the glass-of glass and metal excellent performance is combined
Metal composite structure is applied and gives birth to, and be widely used in microelectronics Packaging, battery, instrument, solar vacuum heat-collecting pipe etc.
Field.
Glass and metal welding are widely used in microelectronics Packaging, relay, solar vacuum heat-collecting pipe etc. and have vacuum gas
The occasion that close property requires.But strength of joint is low, and brittleness is big, is very limited in practical applications.Metal material and glass connect
The main problem connect is: (1) thermal expansion coefficient differs greatly, and stress is concentrated, and a large amount of micro-cracks occurs in postwelding, and joint performance is poor；(2)
Glass material is covalent bond mainly in combination with mode, and metal material is ionic bond and metallic bond mainly in combination with mode, and wetability is very
Difference, interface cohesion are difficult；(3) nonmetallic materials poor toughness is easy to happen fracture.Dissimilar material associative key difference leads to material machine
There are larger differences, such as metal material to have good plasticity and toughness and machinability for tool performance and physical property, and nonmetallic
Material fragility is larger, formd with nonmetallic materials it is complementary, therefore to developing a kind of reliable glass and metal joining techniques
Propose an urgent demand.
Glass and the traditional connection method of metal have anode linkage, soldering, friction welding (FW), electron beam welding, explosion weldering etc..But this
There is the defects of being easy aging, accuracy is low, intensity is low and stomata is more in a little methods.Relative to other welding methods, laser beam control
System is simple, it is easy to accomplish automation, Laser Welding can be with strict control heat input, and thermal deformation is smaller, and heat affected area is small, accuracy
Height, forming are fast；Solderable material category is wide and melt back does not occur, and postwelding weld grain is tiny, and weldquality is high；Relative to electricity
Beamlet welding, is not required to vacuum, is not required to X-ray protection, small to human body injury, and local lap adds in laser beam welding
Hot and cold but remains balance, and molten bath is highly stable.
Kovar alloy, also referred to as Fe-Co-Ni alloy, the alloy within the scope of 20-450 DEG C coefficient of linear thermal expansion be 5.1~
5.5×10-6K-1, molybdenum group glass DM308 is that coefficient of linear thermal expansion is 4.9~10 × 10 within the scope of 20-300 DEG C in temperature-6K-1,
The two similar thermal expansion coefficient at room temperature, can be effectively reduced post-weld stress, obtain good welding point.Suitable for microelectronics
Encapsulation, production relay, solar vacuum heat-collecting pipe etc..
