Abstract
A ceramic particles reinforced composite solder for the soldering of ceramics is prepared from the mixture of Ag powder (65-79 wt.%), Cu powder (20-30) and Ti powder (1-5) and ceramic particles through mixing in ratio of 75-97 vol%: 3-25 vol%. Its advantages are high isotropism and good mechanical distribution in soldered position.
Description
Technical field: the present invention relates to a kind of composition that is used for the brazing solder of fine ceramics connection.
Background technology: in ceramic brazing process, relatively Chang Yong solder is an active solder, this solder has excellent wetting capacity energy, good air-tightness, but because stupalith has lower thermal expansivity with respect to solder alloy, make the bigger coefficient of thermal expansion differences of existence between stupalith and the solder, cause that ceramic joint after the soldering is inner to exist very high unrelieved stress, thereby make that the mechanical property of joint is poor after the soldering.The composite soldering method for welding is compared with common active solder soldering, owing to added wild phase in the solder, make the thermal expansivity of solder integral body reduce, thereby make and mate more between the thermal expansivity of solder and stupalith, help reducing the unrelieved stress of joint after the soldering.But present employed composite soldering mainly is to use fibre-reinforced composite soldering.The composite solderings that the people studied such as Jimin.Cao (Welding Journal as the U.S., Jan.1992:pp21s～24s.), (71.7wt～%Ag, 28wt～%Cu and 0.3wt～%Li) the middle method that adds the nickel plating short carbon fiber has prepared a kind of solder to Powdered silver-bearing copper eutectic solder Bag8a.Wherein the length of carbon fiber is 400 μ m, and by the vacuum coat technology, at carbon fiber outsourcing one deck nickel, the weight ratio of final fiber is 70wt～%Ni and 30wt～%C.When being 20.0%, the volume ratio of nickel plating fiber can obtain the joint that shearing resistance is 8.86 ± 1.16MPa behind this solder brazing.Than volume content is that 0% solder intensity has had large increase.But can not react between carbon fiber itself and the solder, thereby just must carry out Nickel Plating Treatment at fiber surface, making the brazing process more complicated needs to add very big pressure, thereby has limited its application in addition in the brazing process.
Summary of the invention: the object of the present invention is to provide a kind of ceramic granule reinforced composite material that is used for ceramic soldering, it has the technological process of simplification, increases work efficiency, reduces the requirement to brazing equipment, the characteristics of strength of joint height, solder highly versatile.The present invention be the metal-powder A that mixes by Ag powder, Cu powder, Ti powder and ceramic particle B by volume percentage mix form; Metal-powder A accounts for 75～97%, ceramic particle B accounts for 3～25%; Metal-powder A mixes by weight percentage; The Ag powder accounts for 65～79%, the Cu powder accounts for 20～30%, the Ti powder accounts for 1～5%; The diameter of ceramic particle B is 1 μ m～10 μ m.The present invention compares with existing fibre-reinforced composite soldering:
1, wild phase does not need special surface treatment, just can guarantee that the solder matrix has good wetting wild phase particle, makes that corresponding technological process obtains simplifying, and has improved working efficiency.
2, the use of granular wild phase requires to reduce for the force value to workpiece in the brazing process, only needs 0.05MPa, and for fibre-reinforced composite soldering, its corresponding force value is 10MPa.The requirement that this can reduce brazing equipment makes the easier realization of brazing process.
3, for fibrous wild phase, the ordered state of fiber has a significant impact for the final performance of joint, make the thermal expansivity on the different directions that bigger difference is arranged simultaneously, make stressed condition more complicated after the joint brazing, and attempt to realize the fibre array direction is controlled relatively difficulty.By comparison, ceramic particle wild phase enhanced composite soldering has good isotropy, and this can guarantee the good mechanical distribution characteristics of ceramic joint after the soldering.
