The described slurries component that is coated with that is coated with the slurry process use comprises silver-colored slurry, lead borate, rosin and Terpineol 350, wherein silver-colored slurry, lead borate, rosiny weight proportion are: silver slurry 93%, lead borate 5%, rosin 2% add the Terpineol 350 of above-mentioned gross weight 5%-10% then.
Described electroplating work procedure comprises electronickelling and tin-lead alloy plating, first electronickelling, the outer re-plating tinsel of nickel dam.
Adopt processing method products obtained therefrom metal of the present invention and ceramic junction to make a concerted effort, can reach 5kg/mm
2, the physical strength height, high temperature resistant, anti-weldering.
Embodiment
Below in conjunction with specific embodiment the present invention is elaborated
To treat that at first the used vitrified pipe of metallized electric contactor puts into coarsening solution and carry out chemical roughen, increase the contact area of pottery and metal.Used coarsening solution component and proportioning are: chromic anhydride 80g/L, the hydrofluoric acid 130ml/L of concentration 40%, vitriol oil 100ml/L, all the other are water, during use, the coarsening solution temperature is a room temperature, coarsening time 1 hour, put into distilled water then and boil 10min, remove surface impurity, put into 125 ℃ of loft drier inner dryings (2～3) h, with the case cooling, with cooled vitrified pipe, preheating 30min on the hot plate that lies in, vitrified pipe is stuck on the horizontal emulsion coating machine, by drawing in the external diameter pasting, described slurries comprise the silver slurry with oil painting brush, lead borate, rosin and Terpineol 350, wherein silver slurry, lead borate, the rosiny weight proportion is: silver slurry 93%, lead borate 5%, rosin 2%, add above-mentioned silver slurry then, lead borate, the Terpineol 350 of rosin gross weight 8%, it is careful wherein to add the rosiny purpose and be the metal layer that makes behind the sintering, light.Add the solubility promoter lead borate and can reduce the infiltration temperature of metal, improve osmotic effect, strengthen metal layer and ceramic bonding force, metal layer hardness is increased to pottery.The thickness of pasting is greatly about (0.01～0.02) mm.It is taken off be placed in the porcelain dish, and at 105 ℃ loft drier inner drying 30min, taking-up is placed on and is cooled to 60～70 ℃ on the hot plate, vitrified pipe is stuck on the vertical emulsion coating machine, smear end face and endoporus, pasting thickness is at (0.01～0.02) mm, it taken off be placed in the porcelain dish, at 120 ℃ of loft drier inner dryings (2～3) h, finish-drying is to the smell that does not have Terpineol 350; To coat metal slurry, and the vitrified pipe of finish-drying puts with the aluminum oxide refractory slab, can not get together between the vitrified pipe, the vitrified pipe of piling up is put into cabinet-type electric furnace, insulation 30min when rising to 230 ℃ is warmed up to 790 ℃～820 ℃ insulations 4 hours, takes out with the stove cooling.And then return repetition pasting, intensification, sintering, preserving temperature and reducing temperature, this process is carried out three times altogether.Last electronickelling, tin-lead alloy plating outside nickel dam is checked again, promptly finishes the metallization process process of pottery.Tin-lead alloy plating can protect metal layer not oxidized in welding process; improved the wetting property of tin-silver solder again; welding quality is further improved, and the solution pottery is poor with the metal level bonding force, metal layer fragility is excessive, is unable to bear problems such as high/low-temperature impact and shock test.
The vitrified pipe that metallization is finished uses the electrical condenser paper bag good as early as possible behind the cool to room temperature, avoid metal layer oxidation in air.
