Plasma modification of adhesive and substrate surfaces for use in adhesive joint applications

An adhesive joint made by the process of:

• plasma treating a first substrate at a first power level to form a plasma-treated first substrate surface;
• plasma treating a second substrate at a second power level to form a plasma-treated second substrate surface;
• plasma treating a top surface and a bottom surface of an exposed adhesive strip at a third power level to form a plasma-treated exposed adhesive strip;
• joining the plasma-treated first substrate surface and the plasma-treated second substrate surface together with the plasma-treated exposed adhesive strip;
• and
• curing the plasma-treated exposed adhesive strip to produce the adhesive joint.

An adhesive joint made by the process of:

• plasma treating a first substrate at a first power level to form a plasma-treated first substrate surface;
• plasma treating a second substrate at a second power level to form a plasma-treated second substrate surface;
• applying a layer of flowable adhesive onto the plasma-treated second substrate surface and plasma treating the layer of flowable adhesive at a third power level to form a plasma-treated layer of flowable adhesive;
• joining the plasma-treated first substrate surface with the plasma-treated layer of flowable adhesive positioned on the plasma-treated second substrate surface;
• and
• curing the plasma-treated layer of flowable adhesive to produce the adhesive joint.
