Method for manufacturing a body
View Patent ↗A body has at least one first metallic body part and one second metallic body part. The first body part is coated with a nickel-phosphor layer. The first and second body parts are assembled. The first and second body parts are heated such that a soldered connection is produced between the first and second body part as a result of the nickel-phosphor layer.
1. A method for manufacturing a nozzle body comprising a metallic nozzle body and a metallic needle guide section, said method comprising the following steps:
coating the nozzle body having a recess with a nickel-phosphor layer using a wet-chemical process,
inserting the needle guide section partially in said recess of said nozzle body which has been coated by said wet-chemical process,
heating the nozzle body and the needle guide section such that a soldered connection is produced between the nozzle body and the needle guide section as a result of the nickel-phosphor layer,
wherein the nozzle body and the needle guide section comprise a hardenable, temperable metal and the nozzle body and the needle guide section are heated such that a hardening of the nozzle body and the needle guide section takes place when a hardening temperature is reached.
2. The method according to claim 1 , wherein the needle guide section is not coated by a wet-chemical process.
3. The method according to claim 1 , wherein the nickel-phosphor layer contains between eight and twelve percent by weight of phosphor.
4. The method according to claim 1 , wherein the melting temperature of the nickel-phosphor layer is between 850 and 1050 degrees Celsius.
