Hi guys
I am translating a text from English to Persian.I am confused with this word "as-coated" which is a part of this phrase: "Contact angle of as-coated Zn surfaces."
I have never seen "as" as a prefix. Can somebody help me with this word definition?I'd be very grateful.
Thank you in advance👁 Smile :)
Thanks for your answer Barque, but I don't think "as" is abbreviation of anything here. I personally think it refers to some kind of predefined process but I am not sure at all either.anyhow thank you.
You're welcome. And welcome to the forum!
You could measure the contact angle prior to zinc coating which would be different than after zinc coating. The difference would be very slight with zinc plating, but could be quite significant if it were hot dip galvanizing which applies a much thicker coating.

So "as coated zinc surfaces" means the measurements are made after the coating process.

It is possible to assemble parts and galvanize the assembly too. But that is not the case here.
In the metals we use "as formed" to mean the piece of metal's condition as it came off the forming machinery. If it were to be heat treated and plated we would say "with heat treating and finish"; if it were to delete the finish we might say, "as heat treated, less finish". The "as" fits the standard format in our industry.

I am fairly confident that "as" is the word and not an abbreviation or acronym. I am fairly familiar with the plating industry and I have never heard of a process that involved arsenic coating on zinc.

More context might give us a better idea however.
as is
as built
as formed
as heat treated
as plated

The issue seems to be whether there is a hyphen or not and whether that is important in the intended meaning👁 Big Grin :D

I never use the hyphen. I've seen it used. In the context of metal working I don't think it makes any difference. I think it is a word and not an acronym or abbreviation.

I tried Googling "as formed" and "as-formed" and I get 431,000 for each. I don't think Google makes any distinction. I made the request in quotation marks.

This is the same format as "as seen on TV". I think it is just plain English.
Here's a (click) US patent on metal coatings which uses the expression as-coated to mean so-coated (coated in this way) quite frequently.

The conceptual problem I have is inserting this meaning into the OP's phrase - why don't we have a sentence? Perhaps there wasn't one.

I think I'm back with Packard at post #7, considering how a change in thickness would alter an angle of incidence, and vice versa. It's odd to give the angle first, rather than the change in thickness, which would provide the information needed for the other calculations.

In other places we find that the as-coated thicknesses are given as greater than the uncoated thicknesses, as we would expect.

The thickness would clearly make a difference to contact angles of, say, a light source falling obliquely onto the surface.

Regardless, "as" is either an adverb, conjunction, preposition, acronym, or abbreviation. The OP wants to know if it is a preposition. I think it is.
The hyphen should be used in cases where the combination is used as an adjective before a noun, for example: "I would like to see the of this house".
It doesn't look like a preposition to me, but like a replacement for a prepositional phrase that acts adverbially. "As coated" = "In the way {that it was} coated" or "In its state of {having} being coated".

These seem totally compatible to me. Packard and TT have an impressive knowledge on the subject.

I know it's late, and you may be right, Packard, but the OP never mentions prepositions, or parts of speech.

If my hand was held in a fire, I'd call it an adverbial prefix.
We don't have enough context to chose between well-reasoned suggestions, and I am closing the thread.

If IDA.ETMINAN can provide more information about the sentence* and would like the discussion to continue, they should report this post and ask the moderators to re-open the thread.

Similarly, if someone has a similar question and thinks it would be helpful to add it to this discussion, they should report this post.

Until then, this thread is closed.

Thank you all for your contritutions.

Cqgey,

*For example: Where did you see this? What kind of document is it? What is the sentence before the one being discussed?
