摘要
Apparatus for anodising aluminium alloy pistons employed in internal combustion engines. …??This apparatus, where the said piston (1) is connected to the positive pole (3) of a source of direct current, is characterised in that its side surface is equipped, along a directrix situated near the head of a baffle (4) made of electrically insulating material whose surface, on the head side, is placed facing an electrode connected to the negative pole of the said source and pierced by at least one opening (8) permitting the passage of a controlled flow of anodising electrolyte (9) directed towards the head. …??This device finds its application in the production, at a high rate and without recourse to the use of masks or of treatments other than the anodising, of barrier layers limited to the piston heads and which prevent the development of thermal stresses which are detrimental to the proper functioning of the said piston. …IMAGE…
