Title: Composite plating method for iron and steel type material
Inventor: ONODA MOTONOBU
IPC: C25D3/24
Filed: 1980-06-04
Abstract: PURPOSE: To provide excellent adhesiveness for composite plating to iron and steel type materials as well and permit the utilization of the superior performance thereof over a wide range by removing the tough oxide film of the surface of the material to be plated by electrolytic polishing as pretreatment for plating.  
     CONSTITUTION: In composite plating of parts of internal combustion engine parts where abrasion resistance is required, for example, plating wherein SiC power is mixed in an Ni plating layer, the stains of the surfaces of the object to be plated are removed by degreasing. Next, the object to be plated is electrolytically polished by using electrolytic polishing liquid such as, for example, phosphoric acid, sulfuric acid and water (7:2:1), whereby the tough oxide surface of the surfaces is removed. In this treatment, smut sticks on the object to be plated and therefore this is removed by acid immersion (for example in about 20% volume sulfuric acid at about 70W90°C until gas is produced uniformly) or cathodic treatment (for example 20% volume sulfuric acid, ordinary temp.). Finally, composite plating is applied.

In this state, the reference pieces 5 are successively placed just under the coil 4 one by one and the respective intensities of an induction field of them are found by the fluxmeter 3 to calculate the instantaneous value ratio to AC magnetic field intensity with respect to the intensities.  The number of dislocation liners of the arbitrary cut cross section of each of the reference pieces 5 is measured by a transmission type electron microscope to calculate dislocation density. By this constitution, the correlation between the instantaneous value ratio and dislocation density is calculated. Therefore, if correlations are calculated with respect to various materials, the dislocation density of a material to be inspected can be evaluated in a non-destructive manner by using the corresponding correlation.
