Surface treatment was conducted on aluminum alloy, ADC 12, by chemical tin plating, electroless nickel plating, electroless nickel plating (hardening), molybdenum disulfide coating on zinc phosphating, and hard anodizing; and on aluminum alloy, ADC 7, by hard anodizing. Then, the surfaces of above treated alloys were combined with steels, FC 15, S 15C, and S 15C (hardening), and subjected to wear tests to study the effects of surface treatment.The results obtained were summarized as follows:(1) Hard anodizing showed the most remarkable effect and electroless nickel plating (hardening) showed the second.(2) The treatment by hard anodizing was easier to conduct on ADC 7 than on ADC 12, and the wear resistance after treatment was higher in the former than in the latter. It was found that the hardness of the surface treated by electroless nickel plating was increased by heat treatment and its wear resistance was also improved. However, little effects were shown by soft and thin films such as treated by molybdenum disulfide coating and chemical tin plating.(3) When 3 kinds of steel materials, FC 15, S 15C, and S 15C (hardening), were combined with surface treated aluminum alloys, the tendency to toward wear resistance was nearly the same.

The relation between the quenching properties and thermal properties-specific heat, evaporation heat, thermal conductivity and vapor pressure, etc.-was investigated for mineral oils and known hydrocarbons of low molecular weight.The quenching properties of mineral oils are better when the specific heat and the thermal conductivity are largger, and the evaporation heat and vapor pressure smaller, but each cannot explain perfectly the three stages of quenching curves.T1 is dependent linearly on the critical temperature. The critical temperature, dry point, initial boiling point, viscosity and surfactant qualities controll the quenching properties.

The study of magnetic field effects is a relatively new branch of electrochemistry, and although it has grown rapidly in recent years, literature is still fragmentary. Whether or not magnetic field effects are exerted on metals, or on electrolytes, or on both is unknown. The present state of understanding of the effect exerted by magnetic fields on electrodeposition of metals is reviewed. Experimental data have disclosed interesting phenomena. Particular emphasis is placed on the effects of combined electrical and magnetic fields on the qualities and properties of electroplated metals, electrolyte properties, mass transport, electrode kinetics and metal finishing.

Studies were made on the electrodepositions of copper from sulfate or cyanide baths and silver from cyanide bath under ultrasonic vibration. Discussions were made on the difference between presence and absence of ultrasonic vibration on the current-potential curves and the current efficiency-current density curves. It was observed that polarization was appreciably decreased owing to the reduction of diffusion polarization by the application of ultrasonic vibration. It was also observed that surface roughness and grain size of the deposited layer were improved by its application. These effects were particularly remarkable in silver deposition from cyanide baths, where the current density for operation was considerably increased under ultrasonic vibration for reducing the deposition time.
