Observations suggests that there are white particles Ti0.33Al0.67N on membrane layer surface after the particles that were bombarded from alloy target material deposited on the film surface.
Because of the high negative bias that ion deposition of the matrix surface to the temperature increases, cause base material to soften, and negative bias to produce high lattice distortion, causing the residual stress increases, influence film adhesion. 0 50 100 150 200 250 35 36 37 38 39 40 41 42 43 44 45 Ti 0.33 Al 0.67 N Adhesion (N) Substrate Negative Bias voltage(V) Fig 4.

Introduction Edible oil is one of basic materials maintaining human life.
The working principle of screw press involves the rotation of squeezing screw, on the one hand, the materials to be processed are pushed forward, on the other hand, the space volume in pressing chamber is reducing thus producing squeezing effect [1,2].

From the backward radiation profile, one can extract three parameters that have been widely adopted in many previous works for the evaluation of materials with subsurface gradients.
Those specimens were made of AISI 1045 steel (with the surface roughness of 0.027µm in Ra value) and austenitic 304 steel (with 0.022µm in Ra value) as the substrate materials.
