Analysis of variance was used to determine the most significant process parameters affecting the holes roughness.
Feed rates were (1) 0.0075mm/rev, (2) 0.0100mm / rev, and (3) 0.0125 mm / rev under dry drilling test conditions, In the study, a L9(34) orthogonal array was selected to check the influences of the four control factors, the four control factors with three levels each are shown in Table 1.

Coating treatments of cutting tools exhibit similar properties to cooling fluids and can behave as both a protective layer and as a thermal isolation barrier to prevent heat transfer to the tool itself.
The four control factors in descending order of significance are coating layer, feed rate, depth of cut, and spindle speed.

Taking into account the factors of environmental protection, economy and convenience for mass production, and superior corrosion resistance, hot-dip aluminizing is one of the most practical processes utilized on steel.
The Fe-Al alloys layer affects the mechanical properties of welded joint, and makes the required heat input increasing, as a comparison; the uncoated steels optimum heat input is ~3480J/cm.
The heat input of different dipping process corresponding to the best mechanical properties is ~3840J/cm.
The results of optimum heat input show that the ~3840J/cm has the best mechanical properties for Al coating steels.

For comparison purpose, the interaction of stress intensity factors (SIFs) is also examined in the study.
The magnifying factors of time-dependent fracture are obviously larger than that of the linear elastic fracture cases.
The properties are presented in Table 1.
Crack interaction is also affected by the creep exponent n.
For the bi-crack model, the interaction effect represented by C*-integral is influenced not only by the crack configurations but also by the material properties, especially the creep exponent n. 2.
