Description
Technical field
The present invention relates to one kind to improve environment-friendly type hinge basic unit composite film coating technique.
Background technology
Hinge is also known as hinge and is for connection to two solids and allows the mechanical device to rotate between the two, Furniture fittings
Hinge occupies critical positions in accessory；Hinge generally includes the second hinge of the second hinge, the first hinge and connection, first hinge
Bearing pin, usual first hinge are used to be fixed on column, vehicle frame or wall, the second hinge and door Joint so that Men Raoxiao
Axle rotation is with two states opened or closed.During real life, due to the second hinge rotational angle of hinge
Do not have spacing, when causing rotating opening, easily contacted with the column or vehicle body of surrounding so that occur scar on door, influence
Client uses.
Existing hood, trunk lid, lifting door and side door etc. are iron-based material（Density 7.784g/cm3）；Phase
It is lighter than iron-based material, mg-based material（Density 1.738g/cm3）, there is more preferable specific strength, specific stiffness, in body lightening side
There is obvious advantage in face, therefore can be mg-based material by hood, trunk lid, the lifting part design such as door and side door.
But the hinge for location engine cover, trunk lid, lifting door and side door to be arranged on vehicle body is mostly iron
Sill, and mg-based material（Electrical potential difference -2.732V）With iron-based material（Electrical potential difference -0.447V）There are larger potential difference, iron-based
Material directly contacts with mg-based material can produce electrochemical corrosion.That is, hold between the part such as hinge and hood
Electrochemical corrosion is also easy to produce, so as to limit the extensive use of mg-based material.
Because existing insulating corrosion typically uses zincincation, conventional zinc-plated processing include surface cleaning processing,
3 important steps of zinc-plated processing and sequent surface Passivation Treatment in electroplate liquid.Metal Substrate be present in the part of conventional electroplating processes
