Preparation of Metallic Coating on Surface of Diamond Particles by Pulsed Laser Deposition;

The adhesion property of Au/NiCr/Ta multi-layered metallic films was investigated by the indentation method,rolling contact fatigue method and scratch method with both friction and acoustic emission modes.

Au/NiCr/Ta and Au/NiCr metallic multilayers were deposited on A1203 substrate by magnetron sputtering and their critical load (La) was studied by scratch method with friction and acoustic emission mode, moreover, the scratch curve and morphology of metallic films were compared with TiN film.

The relationship between resistivity of metallic film and its surface roughness, residual stress was investigated according to experimental results.

Study on typical rupture modes of thin metal plates under normal impact by conical-nosed missiles;

According to the electromagnetic wavetransmitting equation in good conductor,get the eddy currents 'heating power in sheet metal,then some factors that affect heating power are di-scussed.

In order to study the laws and mechanisms of plasma arc forming,an experimental investigation was performed with 1Cr18Ni9Ti and Q235 sheet metals scanned forward and backward by moving it with respect to the stationary plasma arc.

In this paper,the characters of flexible forming of sheet metal using plasma arc are introduced,and its mechanism is analyzed.

Instead of the rather complicated analytical method and computer aided numerical method for solving two dimensional steady state heat conduction problem of perforated metal sheets this paper proposes an electroconductive paper based thermoelectrical analogy method.

1～8《Sheet metal formability and test methods》were a set of standards for sheet metals forming and their metallurgical industry,which might be divided into three parts.
