Trev,
It was a Loomis that was only about a season old. I've lost the tip guide. It was virtually sawn right through. I have no idea what the history of use was. It's not the only recoils I have seen worn.
If it is any benchmark, I use H&H hardchrome guides on my own rods. I have done for 30 years. If they wore out easily I would not fit them. You do occasionally get a bad batch with poor chrome, but that is very very rare. I rarely see my own rods back for re-ringing. I fit them to rods too that I know the customer is going to putting them through some hard use. Competition boat anglers are particularly hard on rods. It is rare to get them back with worn guides.
As I said if they wore out quickly I would not fit them.
The recoils seem a great idea, but with certain lines they make a screeching noise as you strip line or haul. They set up some sort of vibration in harmony with the speed that the line is moving through them. It's amplified by the blank. It can make heads turn.
A quick google to check on the Vickers figures for surface hardness of chrome against titanium brought up this. (The higher the VHN number the harder it is.)
"Titanium is a much harder metal than aluminum and approaches the high hardness possessed by some of the heat-treated alloy steels. Iodide purity titanium has a hardness of 90 VHN (Vickers), unalloyed commercial titanium has a hardness of about 160 VHN and when alloyed and heat-treated, titanium can attain hardnesses in the range of 250 to 500 VHN. A typical commercial alloy of 130,000 psi yield strength might be expected to have a hardness of about 320 VHN or 34 Rockwell C.
Generally, chrome plated in the bright condition is optimally hard. Bright chromium deposits from conventional baths have a Vickers hardness of 900 to 1000; those from mixed catalyst baths have hardnesses of 1000 to 1100 or higher."
