Cryoblasting as a pretreatment to enhance adhesion to aluminium alloys: an initial study

摘要: Abstract Cryoblasting, which involves bombarding a substrate with carbon dioxide particles, has been shown to have considerable promise as pretreatment for aluminium. Auger electron spectroscopy and contact angle measurements indicated the removal of organic material from metal microscopy roughening effect. Joint strengths obtained single-part epoxide were more than double those after degreasing similar achieved grit blasting or conversion coating. Cryoblasting could be used either “stand alone” alternative solvent first stage, replace solvents, in multi-stage pretreatment. It also effective substrates other
