What are various coatings used on camshafts to harden and protect against wear?

Answer 1

If I recall carburizing is very common , annealing,and probably any hardening process can be used on camshafts.

Answer 2

Camshafts are heat treated in a special oven to harden them. Unless something new has come along in the past few days, noone uses a coating of any kind. It would just be worn off. Keeping oil on the lobes and lifters prevents excessive wear. Some teams probably treat them crogenically, also. What that does is freezes the cam slowly to -300 degrees, leaves it there for a little while, then slowly bring it back up to normal temp. Unless you understand a little about metallurgy, this all probably sounds kinda dumb.

Answer 3

You've completely misinterpreted 2 Timothy 3:16-17. Nowhere in those verses does it say that the Bible is the *only* means of formulating doctrine, but that's how you and many other Protestants choose to read it. In point of fact, "Sola Scriptura" is unscriptural, itself. Paul speaks of clinging to the traditions which have been handed down: 2 Thessalonians 2:15 Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle. And your last comment makes it clear that no matter what a Catholic tells you about the Scriptural foundation for our doctrinal beliefs, you intend to reject it. Even when Scripture is cited, you'll weasel out of agreeing with a Catholic because it's "assuming" an interpretation. That's a classic Baptist/fundamentalist/evangelical take on "Heads I win and tails you Catholics lose" if ever I saw one. If you prefer to worship the Bible instead of God, that's your right and privilege. But your assumption that you alone are correct labels you as both self-righteous and arrogant -- two traits that God hates. And that, my dear, *is* most definitely Scriptural: Proverbs 30:12-13 There is a generation that are pure in their own eyes, and yet is not washed from their filthiness. There is a generation, O how lofty are their eyes! and their eyelids are lifted up. Proverbs 8:13 The fear of the LORD is to hate evil: pride, and arrogancy, and the evil way, and the froward mouth, do I hate.

Answer 4

I boil them in teflon to protect against wear.

Answer 5

It all has to be done when the cam is built. Nothing you add will make it harder.

Answer 6

sometimes they carbon treat a metal to make it harder
