| titleOfInvention | A kind of production technology of guardrail aluminium alloy extrusions |
| abstract | The invention discloses a kind of production technologies of guardrail aluminium alloy extrusions, including the following steps: 1) ingredient: weighing each raw material by following mass percent；2) melting；3) it casts；4) it anneals；5) it is heat-treated；6) it squeezes；7) timeliness；8) cold treatment；9) anodic oxidation；10) differential arc oxidation: after anodized, using differential arc oxidization technique, good reinforcing ceramic membrane is formed on the surface of aluminium alloy extrusions；11) closing process: using the bidirectional pulse closing process of aluminum sulfate solution, confining liquid is aluminum sulfate solution, and ρ (Al3+)=2g/L, pulse frequency 50Hz, positive and negative work ratio 60:35, voltage 0.8V, temperature is 80 DEG C, time 30min.The product that production technology of the invention obtains has the advantages that tensile strength height, and hardness is high, excellent in mechanical performance；Surface hardness is high；Heat resistance and corrosion resistance and good；Insulation resistance is good；The thickness of oxidation film is big. |
