表面硬度怎么换算如题
1)HARDNESS:R15N 80-83 2)FINISH:ZINC PHOSPHATE COAT,150MG PER SQ.FT.MIN 这是我手上一个图纸上面的标注,但没有完全理解它的意思,希望有师傅指导,产品选用的材料是65Mn.我的理解是:1)在15N力的状态下,洛式硬度为80-83度 2)表面需要镀锌,每平方英尺的重量是150MG 我的问题是:1)我的理解有没有错呢?洛式硬度 80-83是很硬的硬度了,是需要淬火么?能达到这个硬度吗?还有硬度之间是怎么换算的?2)一般都会告知镀层的厚度,而这个图纸注明的是多少面积内镀层 的重量,这个应该怎么转换呢?希望知道的告知顺便帮我换算下,最好能附上计算公式.

studied microstructure,hardness,and thermal fatigue beha-
vior of H21 steel with several treatment morphologies (strength-
ening spots,stripes and network) processed by laser surface
remelting and reported that amongst all the three laser-treated
morphologies,strengthening network led to the best thermal
fatigue resistance.Another study [17] reported effects of strength-
ening stripes on the surface of the medium carbon steel and
showed that the specimen with 2-mm-spacing striation had the
highest resistance to thermal fatigue of all.Meanwhile,aforemen-
tioned geometric characteristics of units beneath the treated
surface should be considered as a significant factor influencing
the surface property.On the other hand,the cross-sectional
morphology and mechanical properties of units are both depen-
dent on laser processing parameters.Due to it,it is necessary to
investigate the relationship between the characteristics of biomi-
metic units(size,cross-sectional morphology,and mechanical
property) and processing parameters.
Note that in pulsed laser surface remelting(LSR),a series of
overlapping points make up the scanning track [18].Laser pulse
energy,duration,and scanning speed all place important effects.
In addition to the processing parameters such as pulse energy,
pulse width,frequency and scanning speed,overlapping ratio is
another significant factor in pulsed LSR.

The term core hardness is applicable to carburize and hardened gearing.
Induction hardened gearing may use the term base hardness.
特别是这个 carburize and hardened gearing 怎么翻译比较好呀,急死了
