通常认为,当滑动速度、滑动比和润滑油品种均为相同时,滚滑接触表面的抗胶合能力将随其硬度值增加而增加。但是只在胶合发生前很长时间内表面之间已存在许多金属接触点,此时才可认为这种提法才是确切的。作者曾运用几乎完全阻止金属接触的措施,在大滑动比条件下,在滚动接触疲劳和胶合试验机上进行一系列实验,可以观察到低硬度钢胶合极限的明显提高。举例来说,在高赫兹应力1320MPa(=7.33H_BN/mm~2)和滑动比-130%(PV值等于888MP_am/S)下,直至10×10~6转数时无论胶合或是点蚀均未出现,从而取得了胶合极限的新典型值。
It is generally accepted that when the sliding speed, slip ratio and lubricant type are the same, the anti-seize ability of the sliding contact surface will increase as its hardness value increases. However, it is only at this point that this formulation is accurate only if there are already many metal contact points between the surfaces long before gluing occurs. The authors have used a series of experiments on a rolling contact fatigue and gluing tester with a nearly complete inhibition of the metal contact, with a significant increase in the gluing limit of low hardness steel, observed under conditions of large sliding ratio. For example, both high-Hertz stress 1320MPa (= 7.33H_BN / mm ~ 2) and sliding ratio -130% (PV value equal to 888MP_am / S), up to 10 * 10 ~ Did not appear, resulting in a new typical value of the gluing limit.
