Surface Treatment and Bonding of Ceramics
Ceramics are often combined with other materials including metals, thermoplastics, thermosets and elastomers either by compounding or by joining of distinct parts. In the latter case adhesives are required to bondceramics to other materials. This chapter begins with a short description ofindustrially significant ceramics followed by important treatment methods to impart adhesive bondability to them. Generally ceramic surfaces can be treated in the following manner to impart bondability.
(1) Degreasing and cleaning.
(2) Roughening of the surface by grit or powder blasting.
(3) Acidetch usually using hydrofluoric (HF) or phosphoric (H3PO4) acids.
(4) Silane treatment.
(5) Laser treatment.
(6) Flame treatment.
