Abstract
A surface treating method is described, which method comprising applying, between electrodes, a potential sufficient to cause corona discharge to occur in the presence of a gas which comprises molecules containing at least one atom selected from the group consisting of halogen atom, oxygen atom and nitrogen atom. The resultant corona discharge is applied to an object to be treated for the surface treatment of the object, said object being outside said electrodes. The excellent adhesive surface can be obtained when said object is separated from said electrodes at a distance in the range of 10 mm to 5 m.
Claims21
A surface treating method comprising the steps of:
- applying between electrodes, a potential sufficient to cause corona discharge to occur at an absolute pressure of 300 to 4000 Torr in the presence of a gas which comprises molecules containing at least one atom selected from the group consisting of halogen atom, oxygen atom and nitrogen atom;
- and subjecting an object to surface treatment with the resulting gas generated by the discharge, said object being outside said electrodes and separated from said electrodes at a distance in the range of 10 mm to 5 m.
