In the field of materials, this rapprochement is remarkable, as ascertained by the content of materials conferences in which specific sessions devoted to arts have been included since the year 2000, e.g. at the 18th international conference on “Surface Modification Technologies” (SMT18) in Paris [5].
Moreover, more and more exhibitions promote the dialog between art and materials.
Thermal spray capability of coating thermosensitive materials has long been recognized.
Bright prospects can therefore be expected for the coating of thermosensitive materials such as fabrics.

Introduction Grinding is a material removal process that is used to achieve fine surface finishes, tight geometric tolerances, and complex contours.
So they can’t avoid the defect happening as early as possible, which is the waste of time, labor, and material.
Workpiece material was quenched 45 steel.
