Should I capitalize the suffix -like in a title if it is hyphenated?

For example:

Diamond-Like Carbon Coating or Diamond-like Carbon Coating

Metal-Like Compounds or Metal-like Compounds

Which is correct?

    I wouldn't. A capital after a hyphen is not customary, except in the case of a double-barrelled personal name that is hyphenated. – Colin Fine Nov 17 '19 at 18:38

Precisely because 'like' is a hyphenated suffix, it should not be capitalized in a title.
