The superior wear and corrosion resistance of electroless nickel-based alloys, such as Ni-P and Ni-B, make them favorites as deposited materials for contemporary applications in numerous branches of industry as electronics, mechanical or chemical production [6-9].
In the present work, the Ni-P and Ni-Mo-P deposits are produced and the physical and chemical characteristics of these alloys in the as-deposited and after annealing (at 400°C) states are examined via the electrochemistry and materials analysis instruments.
The electroless deposition procedures of Ni-P and Ni-Mo-P deposits Materials and pre-treatments.

Moreover, the NS provides a deformation temperature decreased by 50 – 100°C as compared to the fine-grained material.
The data of heat treatment for the NS alloy correspond to the Aerospace Material Specification (AMS) requirements.

Introduction With the development of science technology and the improvement of aesthetic awareness, people's requirements of mechanical products streamlined appearance are more and more high.
The dead material (containing chromium, nickel, molybdenum, manganese, titanium, vanadium, etc.) are often hard to process, so we should use extreme pressure or extreme pressure cutting oil emulsion.
The selection of free-form surface machining process parameters is that user input processing object description in the actual production and processing requirements, then reasonably free-form surface machining program can be obtained based on previous cutting tool material selection and the experience.
