The internal friction peaks fall into two groups. When the thickness ratio was greater than 10%, the internal friction peak value was at about 0.035, and when the thickness ratio was less than 10%, the internal friction peak was at around 0.0004. The effect of thickness ratio on system internal friction was very low, which may be duo to the high temperature background friction (HTB) was existed in system internal friction and therefore, the effect of the thickness ratio on the internal friction peak was hided. So that the influence of thickness ratio on internal friction really displayed only HTB was deducted.

Changes in internal friction peaks will fall into two categories,When the thickness ratio is larger than 10%, the internal friction peak value is at about 0.035, when the thickness ratio is less than 10%,the value is at about 0.0004 .The relationship of thickness ratio and system internal friction is unobvious,which may be because the high temperature background friction (HTB) was existed in system internal friction and therefore,the effect of the thickness ratio on the internal friction peak was hidden.So that the influence of thickness ratio on internal friction really was found only when HTB was deducted.

Internal friction peak values cluster around 0.035 when the thickness ratio exceeds 10%, but only around 0.0004 for thickness ratios under 10%  Any effect thickness ratio may have had on internal peak values is almost completely masked by the system's intrinsic High-Temperature Background (HTB) internal friction  Only after HTB has been canceled out does the effect of thickness ratio manifest itself
