摘要： PROBLEM TO BE SOLVED: To effectively use a plating metal body to be melted in plating liquid and reduce cost.SOLUTION: A galvanizing solution 31 is generated by retaining a plating metal body 100 in a cylindrical flow path member 33 in a cylindrical shape and flowing a plating solution 21 into the cylindrical flow path member 33 to contact the plating metal body 100. This enables uniform melting of the whole plating metal body 100, allowing for effective use of the plating metal body 100 without waste. Moreover, a concentration analyzing device 40 controls a flow rate of the plating solution 21 delivered to a zinc melting tank 30 by controlling the rotation speed of a pump 32, and thereby controlling the melting amount of zinc from the plating metal body 100.

摘要： PROBLEM TO BE SOLVED: To provide an alumite treatment method in which a treatment solution can be effectively prevented from adhering to an unnecessary region of a work without using masking rubber.SOLUTION: This method relates to an alumite treatment of a work (turning scroll 20) having a treatment region (wrap wall 22) which is subjected to the alumite treatment and a non-treatment region (end plate 21, boss part 23) which is not subjected to the alumite treatment. While performing the alumite treatment by immersing the treatment region in a treatment solution L without immersing the non-treatment region in the treatment solution L, the circumference of the non-treatment region is covered with a hood 6, and air flow is supplied to the inside of the hood 6 from the outside, thereby eliminating the mist of the treatment solution from the circumference of the non-treatment region (end plate 21, boss part 23) which is not immersed in the treatment solution L.

摘要： PROBLEM TO BE SOLVED: To impart lubricity with durability to an anodically oxidized film by executing electrolysis in an aq. soln. of fatty esters after executing an anodically oxidizing treatment on aluminum. SOLUTION: At the time of executing a surface treatment of the anodically oxidized film of aluminum, the electrolysis is executed in the aq. soln. of the fatty esters after executing the anodically oxidizing treatment on the aluminum. And then, fatty acid is precipitated in the anodically oxidized film. A phosphide is precipitated in the anodically oxidized film by executing the electrolysis in the aq. soln. of the phosphide. The anodically oxidizing treatment is executed in the aq. soln. in which an inorg. acid such as sulfuric acid and chromic acid and an org. acid being an electrolyte are mixed by using aluminum to be treated as an anode and by using a lead alloy as a cathode in 1-4A/dm current density and -5 to 25 deg.C temp. In this way, the surface treated aluminum having a film structure capable of maintaining a lubricating effect is obtained even if the film is weared.

摘要： PURPOSE:To provide wear and corrosion resistances to a low-cost base material by forming several plated Cr layers on the base material in a superposed state and making the surface of the base material or the surface of the 1st plated Cr layer uneven by blasting. CONSTITUTION:The surface 3 of a base material 1 is made finely uneven by blasting and the 1st plated Cr layer 2 is formed on the surface 3. The layer 2 is then blasted to shave the relatively large projections and to form a finely uneven surface 4 having a relatively small difference in height. The 2nd plated Cr layer 5 is formed on the surface 4. When the Cr layers 2, 5 are formed, Cr crystals are preferentially deposited on the tops of the projections of the surfaces 3, 4 at which current density is higher and the deposited crystals grow radially, so the Cr layers 2, 5 have no voids. Thus, a plated Cr film free from defects such as pits and cracks and having superior wear and corrosion resistances is formed.
