introduction：（one）Influence of surface characteristics 1、cleanliness：The metal surface adsorbs a pollution layer and oxide film with low cohesive strength and low surface energy，This will reduce the bonding strength。generally，When the metal surface is clean，Exposure is minimal or even zero。Contact changes with time after material treatment，It is easily polluted by ambient atmosphere in the air，Elevation of contact Angle，about5HThe rear contact Angle tends to stabilize。 Contact Angle and bonding strength before and after surface treatment metal
